Abstract :
The random time delays induced by the network transmission in networked control system (NCS) degrade control performance and can even destabilize the control system. With regards to the long time delay, a distributed model is constructed in this paper. The advanced predictive functional control (PFC) algorithm is introduced in the controller nodes. The network-induced long time delays are specifically considered for predicting the future plant outputs in PFC algorithm. A distributed NCS simulation plant is constructed based on TrueTime toolbox. It is proved that the advanced PFC algorithm can give better control performance than the normal PFC algorithm.
