Passivity-based Event-triggered Fault Tolerant Control for Nonlinear Networked Control System with Actuator Failures and DoS Jamming Attacks

Abstract In this paper, the passivity-based event-triggered fault tolerant control is investigated for networked control nonlinear systems subject to actuator failures under the DoS attacks. Firstly a switched system model is established for networked control systems under event-triggered sampling scheme, and the fault tolerant control is considered for networked control systems(NCSs) under the given actuator failures model. In addition, a new period event-triggered sampling approach was employed, and sufficient conditions are established to ensure the exponential stability, but also ensure strictly passivity for a prescribed passive performance based on the minimal sleeping time of DoS occurring condition. Finally, a simulation result is given to illustrate the effectiveness of the proposed methods.
