摘　　要：以聚丙烯生产为工业背景,针对聚丙烯的生产过程是一个大滞后、时变、非线性的复杂系统,普通PID控制器有参数整定不良,性能欠佳,对运行工矿的适应性很差等方面的问题,本文提出了模糊加PID的控制方案,并结合聚合反应控制的特点,提出了聚合反应温度的模糊加PID控制的方案,并取得了较好的仿真结果。On the background of the polypropylene process, With regard to the practical problems of a kinds of nonlinear,long delay temperature processes,Common Fuzzy controller has its default and disadvantage in nonlinear,long delay temperature processes. On the basis of the soft-sensing model of Melt Index, and the characteristics of the ploy processes, A fuzzy ＆ PID control plan is presented to control the temperate of the process, the simulation results are successful.
