Abstract: In view of problems that uncertain time-delay influences on control performance of wireless network control system and normal PID control strategy cannot meet control requirement of network, the paper proposed a time-delay control scheme of wireless network based on RBF neural network PID control. It used TrueTime toolbox of Matlab/Simulink to build simulation model of time-delay control system of wireless network, introduced design of network module, actuator module and controller module and implementation principle of using RBF neural network to set parameters of PID controller. Simulation result shows that RBF neural network PID control strategy can reduce influence of uncertain time-delay on wireless network control system in some degree and improve stability of wireless network control system compared with normal PID control strategy.
