模糊PID控制在塑料挤出机中的应用研究进展

Application of fuzzy PID control in plastic extruder

综述了模糊比例积分微分(PID)控制方法的研究进展。将模糊PID控制方法应用在塑料挤出机温度控制中,利用模糊控制规则实现PID参数的在线自整定,将模糊化后的信号作为模糊规则输入,可提高温度控制精度。该控制系统提高了塑料挤出机的工作性能和稳定性,以及挤出机成品的质量合格率。

The research progress of fuzzy proportional integral differential(PID)control is reviewed in this paper.Fuzzy PID control can be used for temperature control in plastic extruder,whose fuzzy control rules realizes the online self-tuning of PID parameters.The fuzzy signals are input as fuzzy rules to improve the accuracy of temperature control.The application of the control system improves the performance and stability of plastic extruder as well as the qualified rate of products.
