The control and scheduling co-design of MIMO networked control system are studied in this paper. Considering the MIMO networked control system with multiple sensor nodes, the deadband scheduling strategy with multi-threshold is employed, then the transmit character of the sensor node’s data packets is analyzed. To compensate the effect of the deadband and network-induced delay, an observer is employed, and the closed loop system with the observer and dynamic feed back controller is modeled as a discrete time linear system with uncertainty. Then by the Lyapunov function and LMIs method, the sufficient condition for asymptotic stability is presented, together with the design method for the dynamic feedback controller and observer. Finally, a numerical example is given to validate the method.
