Springer Active Control of Flexible Structures: From Modeling to Implementation (Advances in Industrial Control)

Product Description A complete solution for vibration control problems in structures that may be subject to a broadband primary vibration field, this book covers a range of issues from optimal placement of sensors and actuators to controller implementation and rapid prototyping. Review From the reviews:“Intended for graduate students and practicing engineers, this book treats vibration control for structural systems. It addresses identification of the dynamic model of the structure, placement of sensors and actuators, formulation of control constraints, controller design and simulation, and controller implementation and rapid prototyping. The material is based on the authors’ work on two projects financed by the European Community in the 5th and 6th Framework programs.” (IEEE Control Systems Magazine, February, 2012) From the Back Cover Active Control of Flexible Structures deals with vibration control for large-scale flexible structures which are, or may be, subject to a broadband primary vibration field. The authors present a complete rationale for solving problems of vibration, from experimental structural characterization to controller implementation. In reaching this objective they address the following steps: • experimental identification of the dynamic model of the structure; • optimal placement of sensors and actuators; • formulation of control constraints in terms of controller frequency response shape, based on the specification and characteristics of sensors and actuators; • controller design and simulation; and • controller implementation and rapid prototyping. The experimental identification procedure is based on a gray-box approach tailored to the estimation of modal parameters of large-scale flexible structures. The actuator/sensor placement algorithm maximizes a modal controllability index so as to improve the effectiveness of the control action. Taking into account the physical limitations of sensors and actuators, the controller is chosen as a stable, band-pass MIMO system resulting from the closed-form solution of a robust control problem. The closed-form solution is particularly attractive for large-scale control systems, overcoming possible numerical problems caused by ill-conditioned solutions. Experimental results on an aeronautical stiffened skin panel are presented using rapid-prototyping hardware. Adaptive Control of Flexible Structures will be of interest to academics and practising engineers working on vibration-reduction problems in aerospace and other transportation environments; to civil engineers concerned with seismic vibration in buildings; and to graduate students taking courses in mechanical, aeronautical and control engineering, particularly when involved with smart structures and actuators.   About the Author Alberto Cavallo was born in Napoli, Italy, on 16th March 1964. In 1989 he obtained the Laurea degree at the Università di Napoli Federico II with Laude, discussing the thesis "Robust Stability Analysis for Linear Time-Invariant Systems", and in 1993 he completed his PhD discussing the thesis "A solution to tracking problems via sliding manifolds". Alberto Cavallo is currently Associate Professor both of Advanced Automatic Control and System Identification at the Seconda Università di Napoli. His research interests have dealt with many aspects of the theory of automatic control, including robust control techniques with aeronautical and aerospace applications, with parametric uncertainties and H-2 and H-infinity indices, high-order sliding-manifold control, active control of sound and vibration, modelling and control of smart actuators, control of systems with hysteresis, system identification, fuzzy control, modeling and control of water-resource systems and decision-support systems for hydraulic applications. He has published more than 70 journal and conference papers, and is also local team-leader for several national and international resea
