摘要：
According to the characteristics of the industrial production control system with multiparameters, nonlinear, lager time delay, an on-line parameter Adaptive fuzzy logical Fuzzy-PID controller was put forward. This paper introduces the basic idea of PID and Fuzzy-PID control, the application of the fuzzy-PID controller. The industrial process of liquid mixing is characterized by high nonlinearity, large time delay and multi-parameters. An on-line controller based on adaptive fuzzy logical fuzzy-PID was therefore designed. Then, the two simulation curves of conventional PID algorithm and fuzzy-PID algorithm were compared with each other, and the results showed that the fuzzy-PID control algorithm has a performance of shorter response time, smaller overshoot, better robustness and good stability. It is concluded that the designed fuzzy PID controller is reasonable to improve the control effect, implemented the online self-adaptive adjustment of the liquid mixing parameters.
