Active Control of Flexible Structures From Modeling to Implementation [Paperback]

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.

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.

Adaptive 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 senlS
