Fault tolerant control for networked control systems with data packet drop out based on observer

This paper investigates the control problem of NCS with random data packet drop out under the circumstance of the actuator fault.

Description
Summary:This paper investigates the control problem of NCS with random data packet drop out under the circumstance of the actuator fault. Assume that the data packet drop out obeys the Markov characters, the state observer is designed for the controlled plant and the mathematic model is established for the closed-loop systems. Sufficient conditions for stochastic stability of the closed-loop system are derived by means of Markov jump theory. Then a matrix inequality based approach is presented. Finally, a numerical simulation example is used to demonstrate the effectiveness of the proposed method.
