Abstract

The output feedback control problem is studied for networked discrete-time systems with actuator saturation and packet losses. The proposed output feedback controller is both saturation-dependent and packet-loss-dependent. The resulting closed-loop system is expressed as a switched discrete-time system. A sufficient condition for the local and asymptotic stability of the closed-loop system is developed by using an average dwell-time approach and a saturation-dependent Lyapunov function. The output feedback control law is then proposed in terms of linear matrix inequalities.
