The Research and Application of the PID Controller Based on the Improved BP Network

Abstract:

This paper mainly introduces a PID controller, which is optimized by an improved BP algorithm, and discusses the analysis method of it. It states a way to dynamically adjust the learning rate and the momentum factor through the variety of the input and output of the PID controller to realize an intelligent control. And it connects this control method with the control of the hot winds of the gas in bar furnace of a steel plant to realize a closed-loop control and solve the problems such as the wave of the gas pressure and the insufficiency of combustion. According to the practice, the fluctuation of gas pressure is restricted within 5%, which means that this control method could largely improve the precision of furnace control and further more raise the economic and social benefits.
