| Abstract: | In order to eliminate the effects of network delay on the network control system, this paper uses Elman neural network to predict the system delay sampling value and genetic algorithm to optimize the neural network weights threshold. The experimental simulation shows that Elman neural network optimized by genetic algorithm has good prediction accuracy and dynamic performance and can eliminate the influence of time delay. The method that can eliminate the effects of network delay. |
