摘　　要：为了降低加入自适应控制后被控系统的复杂程度,同时使被控系统在发生故障时仍具有良好的性能,提出了故障检测加自适应重构控制的方法,在系统无故障的情况下不加入自适应重构控制,使系统相对简单,同时对系统进行故障检测;当检测到系统发生故障时,加入自适应重构控制,使系统具有良好的性能。采用的故障检测方法和切换开关既简单又有效。通过对一个飞控系统的仿真研究,表明了该方法的有效性。In order to reduce the complexity of system with adaptive control, and to possess a good system performances when faults occur, a method which combines fault detection with adaptive reconfiguration control is proposed. In order to have a relatively simpler system, the adaptive reconfiguration control method is not added when the system has no faults. Meanwhile, the system is detected. When faults are detected, the adaptive reconfiguration control method is implemented to the system to have good performances. The faults detection method and switch is simple and effective. Simulation results of a flight control system show the efficiency of the proposed method.
