Robust H∞ Control in Active Vibration Control of Piezoelectric Smart Structure

摘要：

This paper mainly analyzes the method of the robust H<x> control and does some experimental researches aiming at the piezoelectric smart flexible structure,under the background of the active vibration control of the aircraft structure. The analysis of the robust control method and the control process are given in this paper. On the basis of these,the structure and the technical parameter of the experiment are described. The structure model of the M1MO system is obtained by the frequency domain identification. According to the frequency domain uncertain and the disturbance,a robust H∞ controller is designed considering the mixed sensitivity control problem. In order to verify the effectiveness and the feasibility of the control algorithm,a simulation is carried out after identifying the control channel. The result of the simulation shows that the control method and the controller design in this paper is useful.
