摘要：

The stripping process in a stripper is characterized by high nonlinearity, large time delay, strong coupling and that the temperature is difficult to control accurately. A stripper temperature control system based on the variable universe fuzzy-PID was therefore designed. With the scale factor chosen according to fuzzy rules and the concept of variable universe combined with fuzzy-PID, a variable universe fuzzy-PID control system was formed. Then, the three simulation curves of conventional PID algorithm, fuzzy-PID algorithm and variable universe fuzzy-PID algorithm of the stripper temperature control system were compared with each other, and the results showed that the variable universe fuzzy-PID control algorithm has a shorter response time, smaller overshoot and better tracking performance.
