According to the requirement of SLR (Satellite Laser Range) using 1.2 m Alt-Az telescope of Yunnan Observatory, and the analysis of function of cascade compensation network in control system and the observation results, the compensation network of servo system of 1.2 m Alt-Az telescope, and the performance of control system after its compensation are discussed in this article. When friction drive is fulfilled by two torque motors, and PD compensation network in servo control system is used, it is found that the capability of rapid tracking of the 1.2 m telescope is actually improved, and the telescope can achieve 10°/s2 of maximum azimuth angle acceleration, 5°/s of maximum azimuth angle velocity, and it can meet the demand of tracking satellites near the Earth.
