Abstract :
With regards to the characteristics of uncertain transmission delay and packet dropout of networked control system (NCS), a distributed model is proposed in this paper. Queuing strategy is introduced both in controller nodes and actuator nodes while the transmission delay and packet dropout between controller nodes and actuator nodes is co-compensated by multi-step increment given by the algorithm of general predictive control (GPC) and BP neural network. Simulation experiments are practiced over Ethernet which embraces both uncertain transmission delay and packet dropout, and it is proved that the scheme of co-compensation remains a good control performance.
