The Research on the Intelligent Controller Based on Elastic-Integral Algorithm and Application on the Water-Level System

摘要

The paper develops a new kind of intelligent PID controller that distinguishes the conventional PID. It makes BP network act on the elastic-integral PID controller, which can adjust its parameters on-line. As the identification controller, RBF neural network identifies the sensitivity of the output to the input, improves the accuracy of the system. The intelligent PID controller realizes the combination of the optimization on the whole performance and the individual parameter. Through the simulation, it shows us that this intelligent controller has the characteristics of better control effect, low overshot and strong robust.
