Bandwidth scheduling of networked control system based on time varying sampling period

For a class of networked control system (NCS) with time delay, the network subsystem and the control subsystem are considered at the same time in this paper. In order to reduce the time delay of the network subsystem, the bandwidth of each closed loop is allocated twice by adjusting the sampling period; In order to guarantee the stability of the control subsystem, the controller is designed with pole-placement method which based on above bandwidth allocation strategy. At last, the validity of bandwidth allocation strategy and the stability of control systems are proved by the simulation results.
