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.
