介紹了通過自適應(yīng)模糊PID 控制器實現(xiàn)氯乙烯聚合反應(yīng)釜溫度控制的設(shè)計思想，由于聚合反應(yīng)釜的大慣性、大滯后的特性，采用常規(guī)的PID 調(diào)節(jié)產(chǎn)生嚴重的滯后效應(yīng)和超調(diào)現(xiàn)象，難以收到令人滿意的結(jié)果。該文利用自適應(yīng)模糊PID 調(diào)節(jié)取代常規(guī)PID 調(diào)節(jié)，取得了令人滿意的效果。仿真結(jié)果表明，該調(diào)節(jié)具有無超調(diào)、響應(yīng)快等優(yōu)點。

GONG Hui-li, YANG Shu-xun (College of Information and Control Engineering, Qingdao University of Scinece and Technology, Qingdao 266042) Abstract: A new method of using fuzzy PID controller with parameter adaption is presented in this paper, which is applied to the chloroethlene polymerizing-kettle system. according to the performance of strong inertia and long time-delay in polymerizing-kettle, PID regulating will bring serious lag effects and large overshoot, it is hard to achieve satisfactory result. The result of simulation indicated: fuzzy PID controller with parameter adaption has such advantages as high control accuracy,
quick response and no overshoot compared with PID controller.
Key Words: fuzzy PID controller chloroethlene polymerizing overshoot
