Event trigger-based adaptive sliding mode fault-tolerant control for dynamic systems

摘要

Dear editor,Fault-tolerant tracking control has recently become an area of research interest, in which fault detection, fault-tolerant control(FTC), and tracking-control techniques are integrated [1, 2]. It is noteworthy that disturbance is a critical factor that degrades system performance [3]. Therefore,disturbance attenuation is indispensable when designing a controller scheme. A common method is to develop a compensator, i.e., an anti-disturbance mechanism could be constructed to compensate for the effects of the disturbance.In previous studies, the disturbance observer based control has been reported as an efficient disturbance-attenuation method [4].
