This paper mainly studies the stability of networked control system with actuator fault and DoS attacks.In the third chapter of this paper,the passivity-based eventtriggered 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 fault model.And sufficient conditions are established to ensure the exponential stability,but also ensure strictly passive for a prescribed passive performance based on the minimal sleeping time of DoS occurring condition;The fourth chapter of this paper studies the finite-time bounded and finite-time stability of linear networked control systems under DoS attacks.In this chapter,the switching system model of networked control systems is given under the event-triggered sampling mechanism,and then the appropriate controllers were designed so that the system can achieve finite-time bounded and finite-time stability under certain conditions given by the theorem.Finally,simulation results are given to illustrate the effectiveness of the proposed methods.
