Abstract: This paper proposes an adaptive predictive control method for networked control systems with random time-delay. By using the Elman neural network, online prediction of the random time-delay of network is realized. Compensation of time-delay is done using an improved implicit generalized predictive control
algorithm with derivative functions. Finally, adaptive predictive control for the networked control system with random time-delay is achieved. Simulation results show that the method has a good compensation effect. It can improve the system output performance and ensure stability and rapidity.

Key words: random time-delay, time-delay prediction, Elman neural network, implicit generalized predictive control, networked control system
