摘要	Because piezoelectric fast mirrors use piezoelectric ceramics as actuatorsa hysteretic nonlinear disturbance can occur during the full travel of a fast steering mirror. To improve the dynamic target tracking performance of optical systems based on piezoelectric fast mirrorsthe effect of hysteresis nonlinearity and the corresponding compensation methods are investigated in this study. Firstbased on the PrandtlIshlinskiiP-Imodela rate dependent hysteresis model in series with the P-I model and the auto regressive empirical model is established. Thena rate dependent model compound control compensation algorithm based on P-I is proposed. Finallyan experimental platform using a piezoelectric fast mirror is built to identify the hysteresis effect of piezoelectric ceramicsand a feedforward controller is designed based on its inverse model. Simultaneouslythe optimization effect of the hysteresis compensation method on the dynamic target tracking system is verified. The experimental results show that the rate dependent model based on P-I is suitable for moving target tracking systems. When the compound control compensation algorithm is appliedthe error suppression bandwidth of the dynamic target tracking system is increased by 26 Hz. Thusthe error suppression capability of the dynamic target tracking system is effectively improved. 2022 Chinese Academy of Sciences. All rights reserved.
