IDENTIFICATION FOR ROBUST CONTROL OF VIBRATING STRUCTURES

Abstract

This paper aims at introducing the reader to the various issues that arise in the development of a coherent methodology for the development of robust control design on the basis of models identified from data. When a reduced complexity model is identified with the purpose of designing a robust controller, the model is just a vehicle for the computation of controller. The design of the identification and of the controller must be seen as two parts of a joint design problem. One of the control messages of this paper is to show that the global control performance criterion must determine the identification one. On the other hand, the paper summarizes the most important approaches of these iterative schemes of identification for robust control. Finally, an academic example is demonstrated for the applicability of the iterative method.
