Abstract: A fast and accurate control system of the piezo-based steering mirror is presented in this paper. The closed-loop control system for scanning and tracking is constructed by combining the piezobased steering mirror, voltage amplifier, displacement sensor and realtime control system AD5435. Then, the feedforward-feedback composite control is designed by using the characteristics of hysteretic dynamic in the piezoelectric system. The fast and accurate tracking performance of the piezobased mirror is demonstrated by the closed-loop control experiment, in which the relative root mean square（RMS） errors of the sinusoidal and triangle trajectories at 50Hz are less than 3.6%. The fast and accurate control method presented in this paper is beneficial to the accurate scanning and jitter suppression in the satellite-based optical-mechanical system.

Key words: piezo-based steering mirror, opticalmechanical systems, mechanical vibration
