    Abstract

    The modified repetitive control and differential feed-forward control are combined to form compound control on the position loop of the servo system of three-axis turret in order to meet the increasing accuracy requirement. According to the structure of the turret servo system, models of current loop, velocity loop and position loop are analyzed and built. And the modified repetitive controller is designed for the position loop. The coupling effect from three frames of the three-axis turret rotating simultaneously is considered in the design. And the speed and stability of three inner frames are analyzed. Simulation results show that the turret has fast position control response, high precision and strong anti-interference using compound control, which can meet the system performance requirements.
