针对一类执行器和关联链接失效的复杂系统,提出了一个间接自适应方法解决容错控制问题.利用自适应律在线估计执行器和链接通道上的故障因子,并基于自适应策略的信息,构造一类通过其他子系统状态链接的分布式状态反馈控制器自动补偿故障影响.基于李亚普诺夫稳定性定理,所得到的自适应闭环复杂系统执行器和网络传输过程故障下可以保证渐进稳定.此方法的有效性最终由一个仿真例子验证.

An indirect adaptive method is presented to solve the fault tolerant control problem against actuator and interconnection faults for a class of complex systems. The adaptation laws are proposed to estimate unknown eventual faults on actuators and interconnection channels on-line. Then a class of distributed state feedback controllers is constructed for automatically compensating the fault effects on systems based on the information from adaptive scheme. On the basis of Lyapunov stability theory, it shows that the resulting adaptive closed-loop complex system can be guaranteed the asymptotic stability even in the cases of faults on actuators and interconnections. The proposed design technique is finally evaluated in the light of a simulation example.
