摘要
建立了某型号导弹在纵向平面内的闭环控制系统模型,通过设计PID控制器参数,使该闭环系统具有一定的容错能力。然后,在被控系统中加入自适应模块,当执行器出现故障时,被控系统的容错能力得到很好的改善。同时,为降低加入自适应控制后系统的复杂性,利用了实际系统与理论模型之间的输出残差来判断系统是否出现故障:当残差小于一定的阈值时,单纯采用PID控制;否则加入自适应控制。仿真结果证明了加入自适应控制的有效性。
The closed loop of a certain missle is establish, and the system has certain ability of tolerating the fault by the design of the PID director. Then the adaptive control is affiliate on the system. It can be found that the ability of fault tolerance of the system is ameliorated. At the same time, in order to reduce the complexity of system with adaptive control. The faults are estimate by the difference between the actual system and the perfect system. If the difference exceeds a certain value, the adaptive reconfiguration control method can be implemented to the system to have good performances. Simulation results show the efficiency of the protposed method.
