Controller Design for the Vibration Suppression of Smart Structures
Development and implementation of piezoelectrically controlled adaptive (smart) structures offer different possibilities for solving many engineering problems involving at the same time solution concepts and methods from different fields and at different levels. This work represents a systematized and comprehensive overview of the most important phases (modeling, control, realization) of a complete development of smart structures, with emphasis on the controller design and its implementation. Model development was treated using the Finite Element Method approach and the system identification. Optimal LQ controller with additional dynamics and the model reference adaptive control are suggested as control techniques for the vibration suppression, which is documented by a "Hardware-in-the-Loop" realization on a complex
application example. Applied control concepts can be successfully used for solving the vibration suppression task in many other practical implementations.
