为解决大型望远镜在深空探测过程中存在的低速爬行问题,提出采用模糊控制算法来代替传统的PID控制器.分别介绍了模糊控制的特性及其基本原理,并具体阐述了模糊控制在大型望远镜中的仿真研究和算法实现；同时分析了一些影响精度的因素.仿真与试验结果对比分析表明,模糊控制算法具有较好的速度稳定性和较高的控制精度.%To solve the problem existing in low speed creep of large sized telescope during deep space exploration, the method of adopting fuzzy control algorithm to replace traditional PID controller is proposed. The characteristics and basic principle of fuzzy control are introduced, and the simulation research of fuzzy control in large sized telescope and the implementation of the control algorithm are described, the factors affecting the accuracy are also analyzed. The contrastive analysis on the results of simulation and experiment shows that the stable speed and high accuracy can be acquired via this method.
