摘　　要：针对光电跟踪伺服系统位置环路控制器传统设计方法的不足，采用一种参数可在线整定的模糊P1D（比例、积分和微分）控制器。分析其结构和设计原理，并在Simulink中建立模型进行相应仿真。仿真结果表明，采用参数模糊自整定的PID控制器能使光电跟踪伺服系统的超调和响应时间减小，为在实际应用中进一步提高其跟踪精度和稳定性提供了理论依据。Due to the shortage of the traditional design method for the position loop controller of optoelectronic tracking system, a parameteronline adjustable fuzzy PID （proportional, integral and differential） controller is used. Its structure and design principles are analyzed, and a simulation is accordingly made by creating a model in Simulink. The simulation results show that it is enable to decrease the overshoot and response time of optoelectronic tracking servo system by using fuzzy self-tuning PID controller, also provides a theoretical basis for further enhancing its tracking accuracy and stability in practical applications.
