| 摘 要： | 在空调系统的温度控制过程中引入模糊控制机理，根据系统的动态特性和行为，采用了对PI控制器的参数在线调整的方法。用PLC语言开发了模糊-PI控制器，应用到实际工程上的结果表明，在参数变化的情况下，模糊-PI控制在解决系统减少超调、缩短调节时间和良好适应性方面优于常规PI控制，在实际控制中达到了良好的控制效果。

| Abstract: | This paper introduces the theory of fuzzy control in the process of temperature controlling, and adopts the means of modulating the parameters of Proportional-Integral-Controller according to dynamic features of the system. By making use of the arithmetic of Fuzzy-Proportional-Integral, the author develops the Fuzzy-Proportional-Integral-Controller on PLC, and adopts it to practice. The results of the application show the superiority of adopting Fuzzy-PI-Controller over conventional PI-Controller in the aspects of reducing excess adjustment, abbreviating adjusting time and having good adaptability. |
