The Design of a Temperature Controller System Based on the Integral Apart Fuzzy PID

Taking into consideration the disadvantages of the traditional PID (proportional integral derivative) control method-low response speed, large overshoot and low control precision-for the temperature control system, the authors propose in this paper an improved control method, which is based on integral apart fuzzy PID. The working principles of this method are expounded, and the relative controller parameters are designed. A comparison was made of the traditional PID control, the fuzzy PID control and the proposed integral apart fuzzy PID control through an experiment with a greenhouse temperature control system, and the results indicated that the proposed integral apart fuzzy PID had faster response, smaller overshoot and higher control precision, thus showing promising potentials for engineering application.
