In order to improve the tracking performance of the galvanometer laser tracking system. A combined control strategy based on feedforward and feedback is designed to solve the problem of uncertainty of the galvanometer motor. This control strategy improves the tracking performance of the galvanometer system through the Zero Phase Error Tracking Controller(ZPETC), additional it uses additive output decomposition to suppress the interference caused by the uncertainty of the system,Then, the residual error can be compensated by the no overshoot PID controller which drived from differential evolution. On the basis of the identification of the galvanometer system and the simulation experiment on Matlab. The system parameter perturbation is simulated by adding disturbance to the identification model. By comparing the tracking error of different controller systems, the function of each controller is verified.Simulation results show that the combined controller can effectively reduce the influence of system uncertainty and ensure the good tracking performance of the galvanometer system.
