Abstract: According to the transmission characteristics of field bus networks,a design approach is developed for NCS(networked control system)with multi packet transmission.In this approach,the controller and sensor nodes are time driven and the actuator node is event driven.The NCS is modeled as switched control systems.Based on the analytical methods of switched systems and stability theory,the sufficient conditions for stability of NCS with multi packet transmission are obtained.At last,the feasibility of the design approach and the validity of the proposed theory are proved through an example.
