Abstract

Aimed at the controlled object's character of long delay-time, this paper presents a strategy that the long delay-time object is remodeled into short delay-time object through decreasing time-delay control, after the adoption of BP neural network PID controller to control the transformed system. In this paper, the three-layer BP neural network is designed and BP neural network PID controller algorithm is analyzed. The simulation results showed that the PID controller based on BP neural network has good control effect in the performance of following, anti-interference, robust.
