根据云南天文台1.2m地平式望远镜对近地卫星激光测距要求,以及对串联校正网络在控制系统中的作用分析和实际观测的结果,详细讨论了1.2m望远镜伺服系统校正网络以及经其补偿作用后系统的控制性能.得到在两点摩擦传动时,使用超前校正网络后,望远镜的快速跟踪性能得到了大大提高,能够达到的方位最大角加速度为10°/s2, 方位最大角速度5°/s,满足跟踪近地卫星的要求. |

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. |
