According to the high frequency response, wide speed control, super-low speed, high precision and strong robustness for flight simulation servo system, an effective internal model PID robust control scheme is proposed in this paper. Based on the discussion of mathematic model of servo system, the internal model PID robust control algorithm is derived and applied in a kind of flight simulation servo system. This servo system adopts three-closed-loop construction of current, speed and position. The simulation experiment results show that the internal model PID robust control scheme has excellent tracking performance, strong disturbance rejection ability and robustness. The proposed control scheme can meet the requirements of the flight simulation servo system very well.
