摘　　要：在地平式望远镜机架的一种俯仰跟踪控制传动链中,其俯仰角度与电机转动角度之间存在非线性关系 ,用经典PID控制方法很难使系统获得很好的动静态性能。将模糊控制和经典PID控制相结合 ,根据参考模型和实际模型的误差动态调整控制器参数 。Owing to the great nonlinearity and time_variation in a kind of telescope control system, good performance of controller can not be gained in traditional way. A controller combining traditional PID control method with fuzzy control method is presented. The parameters of the controller are modified according to the deviation between the reference model and the realistic one. The nonlinearity of driving chain can be compensated.
