The need of vibration control has been spreading in tha last two decades to new application fields such as in the dynamic response of civil engineering structures. In this specific field a promising new technology for control of structural vibrations is based on the use of magneto-rheological (MR) fluid devices in the so-called MR dampers. The present work describes part of the R&D on using a semi-active structural control technique in a civil engineering experimental model frame equipped with a MR damper, developed within COVICOCEPAD project approved in the framework of Eurocores program S3T. Some results are provided associated with the calibration of a MR damper at FEUP as well as on the experimental modal indentification of the dynamic properties os a small-scale metallic frame, without and wich inclusion of a specific MR device. Some numerical results of the controlled frame under simulated earthquakes are given, to be later compared with the experimental results of such frame installed in a Quanser shaking table.

Os avanços da indústria aeronáutica têm sido garantidos pelo emprego de tecnologias inovadoras. Para controle aeroelástico o conceito de estrutura inteligente tem ganho cada vez mais espaço. Uma estrutura inteligente é um sistema de controle estrutural onde elementos estruturais, sensores, atuadores, leis de controle, eletrônica associada e processamento de sinais estão altamente integradas garantindo aumento de desempenho. Os desenvolvimentos nesta área têm sido muito animadores e envolve uma série de disciplinas. Nesse contexto, o presente trabalho tem como meta estudar uma estrutura inteligente onde a lei de controle é representada através da lógica difusa. Esse método não convencional de controle tem proporcionado avanços no trato de sistemas complexos, não lineares e com parâmetros imprecisos e ambíguos. Um modelo em elementos finitos de uma viga inteligente com atuadores piezelétricos incorporados é desenvolvido. O modelo baseia-se nas hipóteses de viga Euler-Bernoulli e no princípio variacional eletromecânico. O modelo em elementos finitos é validado para garantir o uso no projeto do controlador não convencional. Estratégias de controle não convencional baseadas em dois tipos de metodologia difusa para controle...

Os carbonatitos são litologias pertencentes ao grupo de rochas alcalinas e que apresentam grande interesse científico e econômico. Mundialmente se relata a ocorrência de 527 corpos de rochas carbonatíticas, o que salienta a singularidade composicional desse tipo de litologia na geologia global, sendo conhecido apenas um vulcão ativo deste tipo de rocha. No Brasil, é válido fazer especial menção para 5 corpos atualmente sob exploração mineral, nenhum deles situados no Rio Grande do Sul. O trabalho tem como objetivo caracterizar os dois corpos, recentemente identificados, de rochas carbonatíticas no Rio Grande do Sul, denominados Joca Tavares e Três Estradas, cuja descoberta eleva para 529 a contagem de ocorrências mundiais de carbonatitos. O objetivo principal do estudo é a caracterização, espacial e estrutural de cada corpo, a identificação de suas relações com as encaixantes, estabelecimento dos controles estruturais e contextualização geológica no escudo gaúcho, finalizado com a confecção de uma base SIG do projeto. O estudo deu-se a partir da reunião e integração de diversos dados sobre a área, análise detalhada de produtos de sensoriamento remoto disponíveis (fotografias aéreas, imagens de satélite) correlacionados com dados aerogeofísicos. Os produtos assim obtidos foram associados a descrições petrográficas a partir de amostras coletadas em campo e levantamentos no terreno para verificações litológicas e medições de parâmetros estruturais. O carbonatito Três Estradas está encaixado em gnaisses do embasamento (Complexo Granulítico Santa Maria Chico) e possui foliação orientada na direção NE...

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); A produtividade dos poços tubulares profundos em terrenos cristalinos é extremamente variável e depende, além das propriedades intrínsecas da rocha, de fatores externos a ela. Na bacia do rio Jundiaí, Região Sudeste do Brasil, a existência de descontinuidades abertas em situações geológicas favoráveis à recarga constitui o principal fator que influencia a produtividade dos poços. Nesta área, zonas de cisalhamento e zonas de falhas pré-cambrianas reativadas ao longo do tempo geológico controlam a compartimentação morfoestrutural e a deposição de sedimentos cenozóicos. O cruzamento do mapa estrutural com os dados dos poços que explotam o Sistema Aqüífero Cristalino mostrou que poços com produtividade elevada em relação aos demais concentram-se ao longo das estruturas regionais. O forte controle estrutural sobre a produtividade dos poços também é notável em escala de detalhe. Nesta escala, constatou-se que os poços mais produtivos situam-se em áreas onde estruturas rúpteis de direção NW-SE e E-W denotam a ação de esforços transtrativos neotectônicos. A compreensão da história evolutiva aliada à análise do fraturamento mostrou ser uma técnica eficiente e de baixo custo...

The well productivity in crystalline terrains is extremely changeable and depends on external factors, in addition to the intrinsic properties of rocks. In the Jundiaí River Catchment, Southeastern Brazil, the main factor that influences well productivity is the existence of open discontinuities permeability in geologic environments that favor groundwater recharge. In that area, Pre-Cambrian shear and fault zones were reactivated throughout geologic time, controlling the morphostructural compartments and the Cenozoic sedimentary deposition. Superposition of productivity data and structural maps showed that more productive wells are concentrated mainly along the regional geologic structures. The structural control over well productivity is also noticeable in detailed scale. Using fine scale maps we show that the most productive wells are located in areas where brittle structures with NW-SE and E-W directions denote the action of neotectonic transtensional stress. The comprehension of evolutionary geologic history allied to fracturing analysis proved to be an efficient and a low cost technique, which is adequate for selecting areas for further developments using more expensive methods.

This paper studies the effect of time delay on the active non-linear control of dynamically loaded flexible structures. The behavior of non-linear systems under state feedback control, considering a fixed time delay for the control force, is investigated. A control method based on non-linear optimal control, using a tensorial formulation and state feedback control is used. The state equations and the control forces are expressed in polynomial form and a performance index, quadratic in both state vector and control forces, is used. General polynomial representations of the non-linear control law are obtained and implemented for control algorithms up to the fifth order. This methodology is applied to systems with quadratic and cubic non-linearities. Strongly non-linear systems are tested and the effectiveness of the control system including a delay for the application of control forces is discussed. Numerical results indicate that the adopted control algorithm can be efficient for non-linear systems, chiefly in the presence of strong non-linearities but increasing time delay reduces the efficiency of the control system. Numerical results emphasize the importance of considering time delay in the project of active structural control systems.

In this work, a fiber Bragg grating (FBG) sensing system which can measure the transient response of out-of-plane point-wise displacement responses is set up on a smart cantilever beam and the feasibility of its use as a feedback sensor in an active structural control system is studied experimentally. An FBG filter is employed in the proposed fiber sensing system to dynamically demodulate the responses obtained by the FBG displacement sensor with high sensitivity. For comparison, a laser Doppler vibrometer (LDV) is utilized simultaneously to verify displacement detection ability of the FBG sensing system. An optical full-field measurement technique called amplitude-fluctuation electronic speckle pattern interferometry (AF-ESPI) is used to provide full-field vibration mode shapes and resonant frequencies. To verify the dynamic demodulation performance of the FBG filter, a traditional FBG strain sensor calibrated with a strain gauge is first employed to measure the dynamic strain of impact-induced vibrations. Then, system identification of the smart cantilever beam is performed by FBG strain and displacement sensors. Finally, by employing a velocity feedback control algorithm, the feasibility of integrating the proposed FBG displacement sensing system in a collocated feedback system is investigated and excellent dynamic feedback performance is demonstrated. In conclusion...

Magnetorheological actuators are promising devices for mitigating vibrations because they only require a fraction of energy for a similar performance to active control. Conversely, these semi-active devices have limited maximum forces and are hard to model due to the rheological properties of their fluid. When considering structural control, classical theories necessitate full knowledge of the structural dynamic states and properties most of which can only be estimated when considering large-scale control, which may be difficult or inaccurate for complicated geometries due to the non-linear behaviour of structures. Additionally, most of these theories do not take into account the response delay of the actuators which may result in structural instabilities. To address the problem, learning algorithms using offline learning have been proposed in order to have the structure learn its behaviour, but they can be perceived as unrealistic because earthquake data can hardly be produced to train these schemes. Here, an algorithm using online learning feedback is proposed to address this problem where the structure observes, compares and adapts its performance at each time step, analogous to a child learning his or her motor functions.; (cont.) The algorithm uses a machine learning technique...

Large electric transformers such as those used in high voltage substations radiate an annoying low frequency hum into nearby communities. Attempts have been made to actively control the noise by placing a large number of loudspeakers as control sources around noisy transformers to cancel the hum. These cancellation systems require a large number of loudspeakers to be successful due to the imposing size of the transformer structures. Thus such systems are very expensive if global noise reduction is to be achieved. The aim of this thesis is to investigate theoretically and experimentally the use of thin perforated panels closely placed to a heavy structure to reduce the radiation of unwanted harmonic noise. These panels can themselves be vibrated to form a control source radiating over a large surface surrounding the primary source. The problem of the equipment overheating inside the enclosure is alleviated because the holes in the panels still allow natural cooling. An initial study is carried out to determine the resonance frequencies of perforated panels. The use of previously determined effective elastic properties of the panels and Finite Element Analysis to theoretically calculate their resonance frequencies is examined. Secondly the attenuation provided by active noise control using perforated panels as control sources is explored by use of a coupled analysis...

Granite landforms have been interpreted in terms of climatic geomorphology, or morphogenetic regions, but the field evidence overwhelmingly points to structural control. Some features are developed after the exposure of the granitic bodies, for joggling of the brittle crust continues and external agencies also achieve change but the origin of some forms can be traced to the emplacement of the granite bodies, and to strains and stresses developed in magmatic bodies during their intrusion. Various mineral, magmatic and magnetic fabrics are produced. The consolidation of the magma begins at the contact between the emplaced body and the host rock. At this stage, the marginal zone is already crystalline and brittle. Arguably, shearing consequent on continued emplacement causes deformation and the development of planar fractures, some aligned roughly parallel with the cooling and crystallisation surface developed in the uppermost zone of the intrusive body, others imposed by lateral stresses. Differential movements between the sheets produced by shear causes the development of stretching and/or shortening movements. Extension produces a structural fabric that is later exploited by weathering and thus may contribute to the generation of such forms as pseudobedding...

Uranium deposits associated with Paleoproterozoic successor basins were investigated using structural, petrographic, geochronological and geochemical relationships to understand the character and timing of ore-forming fluids and the structural control on uranium mineralization. The work focused on two successor basins that share similar geological characteristics: the Martin Lake Basin in the Beaverlodge area in Canada, and the El Sherana Basin in the South Alligator River area in Australia. The Beaverlodge area records six temporally distinct stages of U mineralization spatially associated with the Martin Lake successor basin. Early minor stages are hosted in cataclasite and veins at ca. 2.29 Ga and in albitized granite in the Gunnar deposit between ca. 2.3 Ga and 1.9 Ga, which predates the main stage of U mineralization of hydrothermal breccias that formed at ca. 1.85 Ga. Later stages of mineralization are related to minor veins at ca. 1.82 Ga linked to alkaline mafic dikes associated with the Martin Lake Basin and to minor veins at ca. 1.62 Ga corresponding to the timing of unconformity-type U mineralization in the overlying Athabasca Basin. The main breccia-type U mineralizing event that affected all deposits in the Beaverlodge area formed at ca. 1.85 Ma from metamorphic fluids at ca. 330oC linked to metasomatism during regional metamorphism of the Trans-Hudson Orogen. The ore-forming fluids were likely derived from metamorphic remobilization of pre-existing U-rich basement rocks...

This paper is concerned with the analysis and design of secure Distributed Control Systems in the face of integrity attacks on sensors and controllers by external attackers or insiders. In general a DCS consists of many heterogenous components and agents including sensors, actuators, controllers. Due to its distributed nature, some agents may start misbehaving to disrupt the system. This paper first reviews necessary and sufficient conditions for deterministic detection of integrity attacks carried out by any number of malicious agents, based on the concept of left invertibility of structural control systems. It then develops a notion equivalent to structural left invertibility in terms of vertex separators of a graph. This tool is then leveraged to design minimal communication networks for DCSs, which ensure that an adversary cannot generate undetectable attacks. Numerical examples are included to illustrate these results.; Comment: 8 pages, 1 figure

The concept of active structural control as a means of structural protection against seismic loads, developed over the last 20 years, has received considerable attention in recent years. It has now reached the stage where active systems have been installed in full-scale structures. It is the purpose of this paper to provide an overview of this development with special emphasis placed on laboratory experiments using model structures and on full-scale implementation of some active control systems. Included in this paper is a report on the formation of a U.S. Panel on Structural Control Research and some discussion on possible future research directions in this exciting research area.

A new robust adaptive structural control design methodology is developed and presented which treats modeling uncertainties and limitations of control devices. Furthermore, no restriction is imposed on the structural models and the nature of the control devices so that the proposed method is very general. A simple linear single degree-of-freedom numerical example is presented to illustrate this approach.

Planning is underway to establish an international full-scale test facility for structural control on the campus of the Hong Kong University of Science and Technology. The purpose of the test facility is to facilitate the development and application of structural response control and health monitoring technologies to improve the safety, serviceability and economy of structures required to resist wind loads, as well as the development of wind engineering information under various wind conditions. The test facility will be centered around a 30-meter high (ten-story) structure with state-of-the-art equipment for the experimental study of structural response control and real-time health monitoring, and it will be available for use by the international structural control community. Current plans are described for the full-scale test structure and associated test facilities, and for a proposed research program, international cooperation and industrial participation.

The knowledge about a planned system in engineering design applications is never complete. Often, a probabilistic quantification of the uncertainty arising from this missing information is warranted in order to efficiently incorporate our partial knowledge about the system and its environment into their respective models. In this framework, the design objective is typically related to the expected value of a system performance measure, such as reliability or expected life-cycle cost. This system design process is called stochastic system design and the associated design optimization problem stochastic optimization. In this thesis general stochastic system design problems are discussed. Application of this design approach to the specific field of structural control is considered for developing a robust-to-uncertainties nonlinear controller synthesis methodology. Initially problems that involve relatively simple models are discussed. Analytical approximations, motivated by the simplicity of the models adopted, are discussed for evaluating the system performance and efficiently performing the stochastic optimization. Special focus is given in this setting on the design of control laws for linear structural systems with probabilistic model uncertainty...

A reliability-based structural control design approach is presented that optimizes a control system explicitly to minimize the probability of structural failure. Failure is interpreted as the system’s state trajectory exiting a safe region within a given time duration. This safe region is bounded by hyperplanes in the system state space, each of them corresponding to an important response quantity. An efficient approximation is discussed for the analytical evaluation of this probability, and for its optimization through feedback control. This analytical approximation facilitates theoretical discussions regarding the characteristics of reliability-optimal controllers. Versions of the controller design are described for the case using a nominal model of the system, as well as for the case with uncertain model parameters. For the latter case, knowledge about the relative plausibility of the different possible values of the uncertain parameters is quantified through the use of probability distributions on the uncertain parameter space. The influence of the excitation time duration on feedback control design is discussed and a probabilistic treatment of this time duration is suggested. The relationship to H_2 �i.e., minimum variance� controller synthesis is also examined.

The primary focus of this thesis is on the modeling and control of a high performance vibration isolation platform used in the protection of mission-critical equipment. The equipment isolation system (EIS) consists of a pair of frames—the bottom-frame contains four concave-up bowls, the top-frame contains four concave-down bowls—between which four rigid steel balls can roll, effectively decoupling the top-frame (and equipment) from the base excitation. In order for the four balls to remain in contact with the dishes during times of large angular rotation, the platform is assumed to conform to a saddle shape. Developing a high-fidelity analytical model to capture the nonlinear nature of the EIS requires (i) enforcement of kinematic rolling constraints to the translational and rotational dynamics of the platform center, (ii) precise measurements of the bowl profiles and an accompanying parameterized model, and (iii) calibrating a linear-viscous damping model to experimental free-responses. To this end, nonholonomic equations of state are found from the d'Alembert-Lagrange principle which incorporates velocity constraints via Lagrange multipliers. The bowl profiles are measured using high-resolution photogrammetry and establish the system's potential energy function. Bowl shape parameters and damping parameters are optimized using a Levenberg-Marquardt least squares algorithm; the damping rate is shown to depend upon the mass of the isolated object.

The present paper implements a novelty semi-active structural control design on a two-story building, with the aim of reducing vibrations caused by transient type loads. The analyzed structure corresponds to an experimental prototype that was fully characterized and modeled according to the diaphragm hypothesis. The controller used was based on the action of a pair of real magnetorheological (MR) dampers whose operation is emulated by the phenomenological model. These mechanisms are governed by a numerical system that is based on non-linear autoregressive model with exogenous inputs (NARX)-type artificial neural networks, which have the ability to determine the necessary optimal control forces and the voltages required for the development of these forces through a prediction model and an inverse model, which are pioneers in this kind of systems. The results obtained show that the control design based on neural networks that was developed in the present study is a reliable and efficient, achieving reductions of up to 69% for the peak response value.
