Abstract：In order to reduce the power demands of the electromechanical actuator(EMA)for a cargo door at a certain type of narrow-body aircraft and effectively control the impact of unknown disturbances on the controller,this paper designs a high-performance servo controller,and proposes a method of integrating velocity PI controller and current hysteresis tracking control by strategy.First,on the basis of deeply ana-lyzing the complex load conditions during the operation of the EMA,the load characteristics of the cargo door in actual working conditions are obtained.And then,based on the load characteristics of the cargo door,the power demands of the controller's motion control process are matched and designed,achieving the design of the controller's architecture and the main functional circuit.Finally,to verify the effective-ness of the proposed control strategy,a model of the controller is constructed by MATLAB/Simulink soft-ware,and the opening-and-closing motion process of the cargo door is simulated.The simulation results show that the proposed control strategy can control the speed fluctuation range within±120 r/min,effec-tively reducing the system's power consumption and significantly enhancing the controller's dynamic re-sponse capability to external disturbances.
