摘　　要：针对快速反射镜工作过程中自身特性和外部环境时刻变化的问题,提出一种将模糊控制理论和传统比例-积分-微分(PID)控制结合的控制策略,即模糊PID控制。根据快速反射镜的机械结构和运动特性,建立快速反射镜动力学模型,设计快速反射镜模糊PID控制器。在Matlab/Simulink中搭建仿真模型,分析对比传统PID控制和模糊PID控制的角度控制仿真结果。实验结果显示,模糊PID控制器实现了快速反射镜的稳定控制,快速反射镜达到稳定的时间为0.13 s,并且有效消除了超调现象。Aiming at the problem that the characteristics of fast steering mirror and the external environment change constantly during the working process,a control strategy combining the fuzzy control theory and the traditional proportional-integral-derivative(PID)control,namely fuzzy PID control,is proposed.According to the mechanical structure and motion characteristics of the fast steering mirror,the dynamic model of the fast steering mirror is established and the fuzzy PID controller of the fast steering mirror is designed.The simulation model is built in Matlab/Simulink and the simulation results of angle control between traditional PID control and fuzzy PID control are analyzed and compared.The experimental results show that the fuzzy PID controller realizes the stable control of the fast steering mirror,and the time for the fast steering mirror to reach stability is 0.13 s,and the overshoot phenomenon is effectively eliminated.
