H∞ control for networked control systems with time delay, data packet dropout and disorder

This paper considers H∞H∞ output feedback control for networked control systems (NCSs) with time delay, data packet dropout and disorder, occurred in both sensor-to-controller and controller-to-actuator channels. A logic data packet processor (DPP) is adopted to solve the data packet disorder and data packet dropout is seemed as a special case of the time delay. Time delay is modeled as Markov chains taking values in a finite set. Finally, the closed-loop system is modeled as a Markov jump system. An output feedback controller is designed to stabilize the closed-loop system with a pre-described H∞H∞ performance index. A numerical example is presented to illustrate the effectiveness of the proposed method.
