摘　　要：快速反射镜(fast-steering mirrors,简称FSM)是一种精确控制光束方向的装置。提出用一种基于压电陶瓷驱动的FSM补偿稳瞄系统中粗级平台的残余误差的方法,可以提高系统稳定精度,同时对采用FSM的高精度稳瞄系统进行了仿真。仿真结果表明:粗级平台稳定误差为110μrad,通过FSM补偿后的系统稳定误差不大于8μrad,即采用该方法可将稳定精度提高一个数量级以上。Fast-steering mirror （FSM） is a device used for controlling the direction of a light beam precisely. This article proposed a method to compensate the residual error of a coarse stabilized platform with FSM driven by PZT to improve line-of-sight stabilization accuracy greatly. The high precision line-of sight （LOS） stabilization system was simulated. The resuits of simulation showed that the stability error of coarse stabilized platform is 110urad, and the stability error after FSM compensation is less than 8 urad. This method can improve the stabilization accuracy at least one order of magnitude.
