This paper considers the reliable extended dissipative control for a class of switched systems with time-varying delay and actuator failure using an event-triggered transmission mechanism. Under the proposed event-triggered mechanism, there is a mismatch between subsystems and their corresponding controllers; a merged switching signal is thus introduced to obtain the closed-loop switched systems. By constructing an appropriate Lyapunov-Krasovskii functional with the merged switching signal, some sufficient criteria are proposed to guarantee the extended dissipativity of the switched systems under asynchronous switching; thus, H ∞ , passivity, dissipativity, and L 2 − L ∞ performance of such switched system can be addressed in a unified framework. The reliable controller gains are achieved by solving a set of linear matrix inequalities. Finally, numerical example and comparison results are provided to illustrate the effectiveness and advantages of the proposed method.
This paper addresses the mixed H ∞ and passive event-triggered control problem for a class of Markovian jump systems subject to sensor saturation and cyber-attacks. By taking the effects of sensor saturation and randomly occurring cyber-attacks into consideration, a closed-loop output feedback Markovian jump system model is established under the proposed event-triggered mechanism.Then, based on Lyapunov stability theory and integral inequalities technique, some sufficient conditions are obtained to guarantee the resulting closed-loop system is stochastically stable and satisfies a prescribed mixed H ∞ and passive performance. Subsequently, the output feedback gains can be derived in terms of linear matrix inequalities by using the matrix decoupling approach. Finally, numerical example and comparison results are provided to show the effectiveness of the approach proposed in this paper.
The robust exponential stabilization for a class of the uncertain switched neutral nonlinear systems with time‐varying delays based on the sampled‐data control is investigated in this paper. The closed‐loop system with sampled‐data control is modeled as a continuous time system with a time‐varying piecewise continuous control input delay. Considering the relationship between the sampling period and the dwell time of two switching instants, sampling interval with no switching and sampling interval with one switching are discussed, respectively. By Wirtinger‐based inequality, Wirtinger‐based double integral inequality, and free‐weighting matrix technique, some delay‐dependent sufficient conditions are given to guarantee the exponential stability of uncertain switched neutral nonlinear systems under asynchronous switching. In addition, sampled‐data controllers can also be designed by special operations of matrices. Finally, two numerical examples are used to show the effectiveness of the approach proposed in this paper.
