Modeling and stability analysis of MIMO networked control systems with data packet dropout and time delay

Considering the MEMO networked control systems with sensors and controller interconnected by network, the sensors and controller are time-driven, and the actuators are on-chip actuators, the problems of modeling and stabilization of MEMO networked control systems with data packet dropout and time delay are studied. By two different methods, one is to introduce a memorizer in the front of the controller to store new data, and the other is to apply the scheduling strategy of the static transmission, such a system is modeled as an uncertain discrete linear system with time-delay, and then the sufficient conditions for the asymptotic stability of the closed-loop system are derived based on the common Lyapunov method. Examples are worked out to illustrate the effectiveness of the method presented.
