摘要
针对高速扫描振镜的传统PID控制存在积分饱和、输出超调以及高频干扰的问题,基于振镜系统的数学模型,采用改进的模糊PID算法,并以改进后的系统模型在Scilab中进行仿真。仿真和实验结果显示,改进后的算法能够有效改善系统的动态和稳态性能,并提高了系统的抗干扰能力。
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.
