Event-triggered control for linear continuous switched singular systems

摘要

Event-triggered control is an effective control scheme, which can reduce the number of samplings without affecting a desirable system performance. The state-based and observer-based state feedback control are studied for linear switched singular systems in continuous-time case. Firstly, we provide an improved event-triggered sampling mechanism. Next, a set of co-design methods are presented, namely, the construction of switching laws, event-triggered scheme and the choice of controller parameters are jointly discussed. Furthermore, the stability conditions are achieved in terms of global E-uniform boundedness providing that the average dwell time is satisfied for considered systems. In our paper, the improved event-triggered mechanism is adopted and obtained results have less conservatism than existing results. Finally, we illustrate the feasibility via numerical examples.
