为降低干扰力矩对光电跟踪系统精度的影响，提出了基于模糊 P ID的光电跟踪系统前馈补偿控制方法。首先，分析了按扰动前馈补偿的控制原理，提出了自适应前馈补偿方法；然后，对用直流力矩电机驱动的光电跟踪系统进行了建模；最后，为光电跟踪系统位置环设计了模糊PID控制器，并在此基础上设计了与之相匹配的自适应前馈补偿函数。仿真结果表明，相对于PID控制的固定前馈补偿控制器，所设计的控制器加快了反应速度，大幅提高了控制精度。

In order to reduce the disturbance effect on the precision of opto‐electronic tracking system ,the feedforward compensation control method for optoelectronic tracking system based on fuzzy PID is proposed .Firstly ,the control principle of disturbance feedforward compensation ,the adaptive feedforward compensation method are analyzed .The modeling of the optoelectronic tracking system driven by DC torque motor is modeled .Finally ,PID controller is designed for the position loop system fuzzy .Based on the controller ,the adaptive feedforward compensation function is designed to match it .The sim‐ulation results show that ,compared with fixed feedforward compensation controller based on PID control of the original ,the designed controller accelerates the reaction speed and greatly improves the control precision .
