The coupling relationship existing between total pressure and liquid level of an air-cushioned headbox in the paper making industry is both complex and nonlinear. This paper analyzes and summarizes the advantages of a traditional BP neural network and PID control methods. A new controller based on BP neural network PID is designed to reduce the influence between the two variables. The controller modifies...
Resistance furnace has the characteristics of nonlinear, time-delay, time-varying and so on. In order to overcome the disadvantage of the traditional fuzzy neural network (FNN) controller with long setting time, an improved fuzzy neural network controller is presented in this paper. It consists of two parts. One is the traditional fuzzy neural network. The other is a compensator, which is used to...
Since the characteristics of time-delay, nonlinear and uncertain model structure, a fuzzy self-tuning PID control is presented in this paper. The fuzzy controller can adapt the control rules to adjust the parameters according to the variation of system characteristics even if the system model is unknown. The approach shows the characteristics of simple structure, outstanding adaptability and satisfactory...
