Active Control of Flexible Structures, 2010 From Modeling to Implementation Advances in Industrial Control Series

A complete solution for problems of vibration control in structures that may be subject to a broadband primary vibration field, this book addresses 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; controller design and simulation; and controller implementation and rapid prototyping. The identification procedure is 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 improving the effectiveness of the control. Considering 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. Experimental results on an aeronautical stiffened skin panel are presented using rapid-prototyping hardware.

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 research projects connected with aeronautic applications of automatic control.He is the author of the book Using MATLAB, SIMULINK and Control System Toolbox: A Practical Approach (Prentice Hall), and has written more than 50 papers for journals and conference proceedings. Giuseppe De Maria was born in Napoli, Italy, in December 1948. In 1973 he received the Laurea degree in electronic engineering from the Università di Napoli. He was Associate Professor of Automatic Control at the University of Napoli Federico II. Since 1992 he has been full Professor of Automatic Control at the Faculty of Engineering of the Seconda Università di Napoli. His research interests include robust control, control of mechanical systems, industrial and advanced robotics, control of aerospace and aeronautical systems, and active noise and vibrationcontrol o
