Output Feedback Stabilization of Networked Control Systems with Random Packet Dropouts

This paper investigates the output feedback stabilization problem for a class of discrete-time networked control systems (NCS) with random packet dropouts. Considering the random packet dropouts occurring in the sensor-to-controller (S-C) and controller-to-actuator (C-A), the resulting closed-loop NCS is modeled as a discrete-time Markovian jump linear system (MJLS) with four modes. Sufficient conditions for existence of a output feedback controller which guarantees the stochastic stability of NCS are established based on stochastic Lyapunov function and linear matrix inequality approach. A simulation example illustrates the validity and feasibility of the results.
