摘　　要：针对弹体扰动对导引头光电稳定系统视轴稳定性的影响,对影响导引头光电稳定系统稳定精度的因素进行了分析,建立了稳定回路模型。基于在线半实物仿真思想,利用dSPACE系统,设计了光电稳定系统视轴稳定精度的测试系统。采用该系统对某光电稳定系统视轴稳定精度进行了测试,并对稳定回路控制器进行在线调整。该方法使设计的光电稳定系统满足了其稳定精度要求,获得比传统方法更高的效率。In order to reduce the effect of missile diaturbance on the stability of line of sight （LOS） of the missile seeker optical-electro stabilization system （OESS） , the main factors affecting the stabiliza- tion accuracy of stabilization loop in the seeker OESS are analyzed, and a stabilization loop model is built. Based on the hardware-in-loop simulation theory, a dSPACE measurement system of the LOS stabilization accuracy is designed to measure the LOS stabilization accuracy of the seeker OESS, and the controller of stabilization loop is designed on the basis of the measurement data on-line. Through this method, the sta- bilization accuracy of the seeker OESS can meet the system stabilization accuracy requirement, and the controller is efficiency greater than that of obtained through the classic method.
