摘　　要：文中针对地地导弹半自动化瞄准系统,瞄准时间长、精度不高的缺陷,提出一种模糊-PI复合控制器设计方法,该方法在瞄准误差较大时采用模糊控制方法以实现对瞄准误差的快速跟踪;瞄准误差较小时,采用PI控制以消除稳态误差。最后,通过仿真验证了所设计的控制器可以大大缩短瞄准时间,而且具有很高的瞄准精度,具有较好的工程参考价值。A new method for designing ballistic missile collimated system is presented. For overcoming the disadvantage of semi-automatization collimated system, this method uses fuzzy-PI multi-controller to track the collimated error. When the error is large, the fuzzy control is used to eliminate the error quickly, and when the error is small, the PI con- trol is used to enhance the precision. In the fist part of his paper, the model of the collimated system is given. Then, the method of designing the fuzzy-PI multi-controller has been demonstrated, and it is proved by simulation that this collimated system has the performance of higher collimated precision and using less time compared with the semi-automatization collimated system.
