摘要
文中提出了在随机框架下对混杂系统主动容错控制的建模方法。该模型采用两个不同的马尔可夫过程来分别表征故障过程和故障诊断与辨识(FDI)过程。在该模型下,文中给出了混杂主动容错控制系统在任意切换下渐进稳定的充分条件,并将该条件推广到切换线性系统的情况下。最后讨论了在该模型下可以进一步开展的研究。
The formulation of active fault-tolerant control （AFTC） of hybrid systems under stochastic framework were presented where two different Markov processes wree employed to represent the failure and the fault detection and identification （FDI） processes, respectively, A sufficient condition for the asymptotic stability under arbitrary switching was derived using common Lyapunov function. In particular, the stability condition for switched linear systems with actuator failure is considered. Finally. further research directions are discussed.
