As the core actuator of high-precision optical systems, the control strategy of fast steering mirror directly affects the performances of the system. Traditional control strategy of the fast steering mirror relies on independent control boxes and linear power amplifier modules, resulting in large volume, high heat and limited application of fast steering mirror control systems. However, the fast steering mirror driven by metal-oxide-semiconductor field-effect transistor (MOSFET) switch values is difficult to achieve accuracy requirements in control. A control strategy combining open-loop zero pole configuration and proportional integral derivative (PID) through modeling and frequency sweep analysis of fast steering mirror is proposed, which is simulated on the hardware of the fast steering mirror. Experimental results show that this control strategy can ensure the high-precision requirements of fast steering mirror control without relying on additional controllers and driving modules.
