Active control of flexible structures: from modeling to implementation

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." Shows the reader how to deal with not only vibration induced by distinct resonance peaks butalso with those caused by broad-band disturbance Shows the reader how to testresults quickly using rapid prototyping technology Relies on well-know robustoptimal control strategies INDICE: Introduction.- Modeling of Flexible Structures.- Identification ofFlexible Structures.- Active Control of Flexible Structures.- Implementation Issues.- Experimental Results.- Appendix.
