Download or read book Design of Optimal Feedback for Structural Control written by Ido Halperin and published by CRC Press. This book was released on 2021-07-01 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural control is an approach aimed at the suppressing unwanted dynamic phenomena in civil structures. It proposes the use of methods and tools from control theory for the analysis and manipulation of a structure’s dynamic behavior, with emphasis on suppression of seismic and wind responses. This book addresses problems in optimal structural control. Its goal is to provide solutions and techniques for these problems by using optimal control theory. Thus, it deals with the solution of optimal control design problems related to passive and semi-active controlled structures. The formulated problems consider constraints and excitations which are common in structural control. Optimal control theory is used in order to solve these problems in a rigorous manner. Even though there are many works in this field, none comprise optimization techniques with firm theoretical background that address the solution of passive and semi-active structural control design problems. The book begins with a discussion on models which are commonly used for civil structures and control actuators. Modern theoretical notions, such as dissipativity and passivity of dynamic systems are discussed in context of the addressed problems. Optimal control theory and suitable successive methods are reviewed. Novel solutions for optimal passive and semi-active control design problems are derived, based on firm theoretical foundations. These results are verified by numerical simulations of typical civil structures which are subjected to different types of dynamic excitations.

Download or read book Stochastic Optimal Control of Structures written by Yongbo Peng and published by Springer. This book was released on 2019-06-27 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book proposes, for the first time, a basic formulation for structural control that takes into account the stochastic dynamics induced by engineering excitations in the nature of non-stationary and non-Gaussian processes. Further, it establishes the theory of and methods for stochastic optimal control of randomly-excited engineering structures in the context of probability density evolution methods, such as physically-based stochastic optimal (PSO) control. By logically integrating randomness into control gain, the book helps readers design elegant control systems, mitigate risks in civil engineering structures, and avoid the dilemmas posed by the methods predominantly applied in current practice, such as deterministic control and classical linear quadratic Gaussian (LQG) control associated with nominal white noises.

Download or read book Feedback Control Theory written by John C. Doyle and published by Courier Corporation. This book was released on 2013-04-09 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: An excellent introduction to feedback control system design, this book offers a theoretical approach that captures the essential issues and can be applied to a wide range of practical problems. Its explorations of recent developments in the field emphasize the relationship of new procedures to classical control theory, with a focus on single input and output systems that keeps concepts accessible to students with limited backgrounds. The text is geared toward a single-semester senior course or a graduate-level class for students of electrical engineering. The opening chapters constitute a basic treatment of feedback design. Topics include a detailed formulation of the control design program, the fundamental issue of performance/stability robustness tradeoff, and the graphical design technique of loopshaping. Subsequent chapters extend the discussion of the loopshaping technique and connect it with notions of optimality. Concluding chapters examine controller design via optimization, offering a mathematical approach that is useful for multivariable systems.

Download or read book Stochastic Control in Structural Design written by D. G. Carmichael and published by . This book was released on 1981 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deterministic optimal control has contributed to the field of structural optimization through the introduction of new concepts, alternative ways of viewing design problems and a systematic methodology for solving design problems. It remains to show the applicability of stochastic control to the probabilistic structural optimization problem. Here the applicability is not so self evident but its usefulness can be demonstrated. The paper examines open-loop, closed-loop, open-loop feedback and m-measurement feedback control policies and gives the optimal result for the general nonlinear structural optimization problem. The special linear-quadratic problem is examined along with numerical approaches to solving the general nonlinear problem, including the method of stochastic approximation. The design of members in flexure and compression is used to illustrate the methodology. (Author).
Download or read book Seismic Control Systems written by S. Syngellakis and published by WIT Press. This book was released on 2013 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthquakes remain largely unpredictable and potentially catastrophic, a matter of continuous concern to communities in affected zones. Scientists and engineers have made a considerable effort to mitigate their consequences through the design of effective protective devices. New concepts have recently been developed to address the requirements for better structural performance and a more effective use of new materials at a lower cost.This book disseminates knowledge and increases awareness on this very critical subject and thus ultimately contributes to a safer structural design against earthquakes. It comprises a number of articles taken from recent editions of Transactions of the Wessex Institute covering a wide range of topics within the subject of seismic protection through vibration control devices.The first four papers provide a very comprehensive review of existing seismic control designs highlighting their variety, the effectiveness of their performance, as well as the extent of their use for the protection of various types of structures world wide. Most articles deal with anti-seismic devices implementing passive control of structural response through seismic isolation and energy dissipation. Testing and modelling energy-dissipating systems are also extensively covered in the book.It is also important to understand how existing structures fitted with seismic control devices perform against earthquakes. Two such case studies are included in the book; a roof isolated from the top of an existing structure and a bridge supported on both isolating and damping systems. Finally, new analytical approaches for optimising the performance of tuned mass dampers are detailed in two companion papers.
