Abstract

To the characteristics of the large delay and uncertainty of superheated temperature, a new cascade control system is presented based on control's history. Based on the analysis of the control objects'dynamic characteristics, historical control information(substituting for the deviation change rate)is used as the basis for decision-making of the fuzzy control. Therefore, the changing trend of the controlled variable can be accurately reflected. Furthermore, a proportional component is introduced, the advantages of PID and fuzzy controllers are integrated, and the structure weaknesses of conventional fuzzy controllers are overcome. Simulation shows that this control method can effectively reduce the adverse impact of the delay on control effects and, therefore, exhibit strong adaptability by comparing the superheated temperature control system by this controller with PID and conventional fuzzy controllers.
