摘　　要：论述了SIMAT IC S7-300可编程控制器在塑料挤出机温度控制系统中的应用,控制回路采用单参数模糊P ID(比例、积分、微分)脉宽调功法。控制系统把单参数模糊P ID控制和PLC(可变程序逻辑控制器)的逻辑判断指令结合起来,使P ID控制更为灵活,能较好地满足生产过程的要求。详细描述了该系统的工作原理和PLC的硬件组成、软件编制。A novel temperature control system for plastics extrusion is presented based on S7-300. The single parameter PID fuzzy control and pulse width modulating are used. In the proposal system the single parameter PID fuzzy algorithm and PLC logic instruction is combined. Which makes the system more flexible. It can satisfy the request of the production processing. The principle, hardware and software is described in detail. The monitor computer of PLC is simplifying introduced.
