Fuzzy-PID based heating control system

The Fuzzy-PID is combined fuzzy control and PID control, and it can realize the self-adaptive of Kp, Ki and Kd of the PID. So the Fuzzy-PID not only has the advantage of easy to application, strong robust, but also can be more widely used and have higher performance than normal PID. In this paper, we use a new method to design the Fuzzy-PID and apply it in the Scientific CCD camera's shutter heating system. As compared to the normal PID, the Fuzzy-PID algorithm has a better performance on reducing the temperature overshoot, reducing the adjusting time and improving the control accuracy.
