Output feedback control for networked control systems with packet dropout

This paper is concerned with the stabilization problem of networked control systems where the main focus are the packet-loss, time delays and unmeasured system states. Here a state observer is designed for estimating the states and compensating for time delay and data dropout, then the whole closed system is modeled as asynchronous dynamical system constrained by configuration event rate. By using Lyapunov principle, sufficient and necessary conditions for exponential stability of the closed loop system is obtained, and the states feedback controller design method is presented. Simulation example for the design is done in truetime in matlab and the result shows the validity of the method.
