In order to reduce the effect of carrier disturbance on the stability of line of sight (LOS) of the optical-electro stabilization system (OESS), a stabilization accuracy model of stabilization loop is built, and the main factors affecting the stabilization accuracy of stabilization loop in OESS are analyzed. Based on the on-line semi-physical simulation theory, a dSPACE measurement system of the LOS stabilization accuracy is designed to measure the LOS stabilization accuracy of the OESS, and the controller of stabilization loop is designed on the basis of the measurement data on-line conveniently. Experimental results show that the stabilization accuracy of the OESS with this method is 0.24mrad which is met the requirement. The novel method of stabilization accuracy measurement and controller on-line debugging for OESS can achieve higher stabilization accuracy and a greater efficiency over the classic method, and also indicates that this novel method is efficient and should be effective on further stabilization accuracy research of OESS. |
