Abstract EN
For the networked control system with limited bandwidth and flexible workload, a dynamic intelligent feedback scheduling strategy is proposed.
Firstly, a monitor is used to acquire the current available network bandwidth.
Then, the new available bandwidth in the next interval is predicted by using LS_SVM approach.
At the same time, the dynamic performance indices of all control loops are obtained with a two-dimensional fuzzy logic modulator.
Finally, the predicted network bandwidth is dynamically allocated by the bandwidth manager and the priority allocator in terms of the loops' dynamic performance indices.
Simulation results show that the sampling periods and priorities of control loops are adjusted timely according to the network workload condition and the dynamic performance of control loops, which make the system running in the optimal state all the time.
