A pre-amending method was studied and implemented to the fast steering mirror (FSM) execute component to improve the dynamic response characteristics of an opto-electronic fine tracking system based on voice coil actuator(VCA) FSM. A feedforward adjusting step was additionally applied for optimizing the control of the FSM according to the target position variation obtained by a target detection and recognition component. The configuration and principle of the opto-electronic fine tracking system based on FSM were described, and the control of the VCA driven fast steering mirror was modeled. Further, the feedforward-feedback control method was implemented. An experimental system consisting of a target simulation part, a target imaging and detection part, and a target tracking part was constructed to test and verify the method. The results show that the delay of the system is shortened from 2.9 ms to 0.8 ms, and the dynamic response bandwidth is improved from 20 Hz to 45 Hz. The pre-amending control method can significantly reduce the phase lag of the opto-electronic fine tracking system and improve the systematic response characteristic.
