Research on Control Algorithm of Linear Rudder Motor Servo Loading System

This paper mainly focused on the theoretical studies of the linear rudder electric servo loading system. The mathematical model of motor servo loading system is established. Then, the disturbance force which would influence the system's dynamic performance is analyzed. In order to improve the accuracy of loading system, a feedforward-PID control algorithm is proposed. The algorithm can improve the performance of loading system. Digital simulation and analyses about the system are carried out, the result of simulation proved the algorithm is feasible.
