摘　　要：温度控制作为塑料挤出机工业过程中的重要步骤,决定了塑料挤出产品的质量。在工业过程中,塑料挤出机的温度控制具有非线性和滞后性,导致了稳定性和控制精度差的问题。为了提高塑料挤出机温度控制的稳定性和控制精度,本实验针对整体式料筒结合改进型格型联合处理器研究温度控制策略。由于改进型格型联合处理器的权值系数可以在每个回路内独立调整,故其能够达到很高的建模和控制精度。本实验采用改进型格型联合处理器对塑料挤出机温度控制进行仿真实验,验证所提控制器的稳定性和控制精度。As an important step in the industrial process of plastic extruder,temperature control determines the quality of plastic extrusion products.In the industrial process,the temperature control of plastic extruder is nonlinear and hysteretic,which leads to the problem of poor stability and control accuracy.In order to improve the stability and accuracy of temperature control of plastic extruder,this paper studies the temperature control strategy for the integrated barrel combined with the improved lattice joint processor.Because the weight coefficient of the improved lattice joint processor can be adjusted independently in each loop,it can achieve high modeling and control accuracy.In this paper,the temperature control of plastic extruder is simulated by improved lattice joint processor to verify the stability and control accuracy of the controller.
