Abstract

The typical structure of the servo system of a E-O Stabilization and Tracking Devices(EOSTD) was introduced. Based on dSPACE hardware-in-the-loop simulation system

the common design process of velocity stabilization was researched. Aiming at the phase lag phenomena caused by digital frequency characteristic test

the phase compensation formula was proposed and some nonlinear compensation methods were discussed to achieve high stabilization precision. Analyzing deeply on the frequency coupling of the position tracking loop and the velocity stabilization loop

the corresponding de-coupling method and the ideal model of the position loop and the velocity loop above were presented. Based on that model

the conception of the isolation degree was discussed. Five typical instances were simulated

the position tracking and line of sight stabilization results were provided in the end. The results show the validity of the concerned conception.
