摘 要：A novel integrated design scheme of dynamic dwell time scheduling strategy, dynamic bandwidth allocation policy, and quantized control for networked control systems(NCS) with time delay and communication constraints is proposed in this paper. A scheduling policy is raised to accommodate a limited number of node-controller connections which depend on the periodic communication sequences and dynamic dwell time. Then, the neural network technique is employed to dynamically allocate bit rate for the scheduling nodes. The networked control systems are modeled as discrete-time switched systems with bounded disturbances. Finally, a design procedure for the state feedback controller is presented to guarantee asymptotic stability of the NCS. A simulation example is given to illustrate effectiveness of the proposed method.
