For the sampling period affects the performance of the networked control systems, a dynamic scheduling strategy based on the prediction and feedback control of networked control systems is proposed. First the paper proposes one kind of dynamic weight adjustment strategy of control loop based on transmission error, and then uses the least squares support vector machine algorithm to predict the packet transmission time.Finally, under certain conditions of the network bandwidth, changing system sampling period constantly to optimize the performance of the network control system by network utilization, packet transmission time and dynamic weight coefficient.
