The transfer function model of the system was established,and the influence of the servo pa-rameters on the response characteristic was analyzed. The position output of the motor was controlled by the proportional integral deriv-ertive(PID)controller to reduce the output error of the motor position. The system modeling and simulation analysis were carried out by Matlab/Simulink,and the control parameters were selected by genetic algorithm,which improved dynamic response characteristics of the system,and has achieved good control effect.
