Fault tolerant control of networked control system with the failure actuator

This paper presents a fault-tolerant controller design method to deal with general actuator failure in networked control systems (NCSs). First, considering non-ideal network quality of services, such as, networked-induced delay, packet-loss, error sequence, a continuous model for NCSs is established. Next, a stabilization criterion is provided to ensure the stability of the studied system. Due to the introduction of the free weighting matrices to deal with the cross-terms in the derivation, and the convexity of the matrix function to deal with coupled delay items, the less conservative results can be expected. Finally, a numerical example is provided to show the effectiveness of proposed method.
