Development of temperature equipment based on predictive Fuzzy Control

Aiming at the properties of nonlinear time varying and delay, this paper used fuzzy control with prediction algorithm to control the speed of temperature and keep the load stable. A two-dimensional predictive fuzzy controller was built, Whose input signals were deviation and its change rate of the rotational speeds of cylinder and screw conveyor and output signal was the controlling Plus of servo stepping. Time delay that frequently occurs in the temperature control, predictive Fuzzy Logic Controller (FLC) has the advantages of free from the plant model, strong robustness and good stability against disturbances. So a two predictive fuzzy control scheme was developed to handle processes with large time delay. In the lower level, human simulated intelligent predictive fuzzy controller, which combines such advantages as model-free.
