Event-triggered control for networked control systems with quantization and packet losses

Abstract

Problems of the quantized stabilization for event-triggered networked control systems (NCSs) with packet losses are addressed. To reduce the communication resources in NCSs, event-triggering scheme is adopted and designed. A NCS model is proposed which considers quantization, plant uncertainty, event-triggering scheme and packet losses simultaneously. Sufficient conditions for the stabilization and control design are derived using the Lyapunov functional approach and control synthesis of event-triggered networked control systems are established in terms of linear matrix inequalities. Moreover, the maximal allowable number of successive packet losses in NCS is estimated. A numerical example is given to illustrate the effectiveness of the proposed method.
