Abstract:

With the development of laser imaging technology, the traditional PID control for high-speed scanning galvanometer has the problems of integral saturation, output overshoot and high frequency interference. Based on the mathematical model of the galvanometer system,the improved system model using fuzzy PID algorithm is simulated in Scilab. Simulation results show that the improved algorithm can effectively improve the dynamic and steady-state performance of the system and improve the anti-interference ability of the system.
