Abstract

This paper investigates the modeling and H∞ composite control of the coupled hysteretic dynamics in a piezoelectric micro-displacement system (PMS). First, the coupled multi-field hysteretic dynamics with physical meanings is presented for PMS. Next, the composite control analysis of the hysteretic dynamics is proposed. Then, a H∞ synthesis controller is designed by using the simplified hysteretic dynamics. To enhance the H∞ performance, the inversion-based feedforward compensation is augmented. The proposed H∞ feedback control and the inversion-based feedforward can be designed separately. Finally, the experimental studies are provided to demonstrate the proposed H∞ composite control approach.
