Abstract: This article described the composition of laser marking galvanometer scanning system. In connection the improvement of the performance of the system dynamic performance, highspeed response and accuracy of marking galvanometer servo scanning system with traditional PID control method, and based on establishing the galvanometer system mathematical model, studied the PID+ feedforward control model . Therefore,it proved that the PID+ feedforward control could gete the rapid response and accuracy through the simulation and experiment.
