摘　　要：光电跟踪系统通常采用跟踪偏差反馈闭环控制,若同时采用速度前馈复合控制可以有效提高系统跟踪精度,分别使用了卡尔曼滤波器和跟踪微分器两种算法求取跟踪速度信号,通过仿真分析和工程应用,确认卡尔曼滤波器求取的速度信号更准确,噪声更小,更适合于光电跟踪系统的前馈复合控制。Photoelectric tracking system usually adopts tracking deviate feedback closed-loop control,if speed forward feedback control is used at the same time,the tracking precision will be improved effectively. This paper uses Kalman filter and tracking-differentiator respectively to calculate tracking speed signal. Through simulation analysis and actual application,speed signal calculated by Kalman filter is confirmed more accuracy, and noise is smaller, it's more suitable for forward feedback control of Photoelectric tracking system.
