Networked control system time delay compensation based on improved implicit GPC

The ELM is used to predict the delay, and combines with implicit generalized predictive control (IGPC) to compensate time delay in this paper. The random time-delay in the networked control system (NCS) can usually deteriorate the control performance and stability of networked control system. In order to solve this problem, this paper puts forward the networked time delay in a short time based on extreme learning machine (ELM). At the same time, IGPC is used in this networked control system with the results of ELM. The simulation results show that the method in this paper make the output of the system track the reference trajectory well and performance better than traditional generalized prediction algorithm.
