| 摘 要： | 针对塑料挤出过程中熔体温度的时滞性和非线性,在对传统挤出机温度控制方法深入分析的基础上,提出一种基于模糊-PID的挤出机温度控制方案,并给出实现方案的控制系统结构和设计方法,同时采用MATLAB进行仿真,结果表明该方案能有效地提高挤出过程的熔体温度控制精度,且在模型参数发生变化时仍能获得良好的动态响应性能。

| Abstract: | Considering the nonlinearity and time delay of the extruding process,on the basis of deep analysis of the traditional PID,puts forward a control strategy of extruder temperature,which based on fuzzy-PID gives the structure and design process of the system based on this strategy.And simulated the system by MATLAB 7.0.The results show that the strategy cans achive accurate control of melt temperature even when the parameters of the model are changed. |
