Application of cylinder temperature control

The temperature of the injection molding machine is an important parameter in the injection molding process. Effective control of the temperature of the injection molding machine is an important part of ensuring the molding quality of plastic products. However, the injection molding machine barrel temperature system is a complex system with multiple variables, discreteness, intermittent operation, large hysteresis, nonlinearity, and strong coupling, which requires human participation. Due to the complexity of the heating process, it is difficult to establish a [sensitive word] mathematical model of the control system, which makes barrel temperature control a difficult point in the design of the injection molding machine controller. In addition, in the design process of the barrel temperature controller of the injection molding machine, the controller's performance such as good robustness and low algorithm complexity is a parameter index that cannot be ignored. At present, the PID control method is widely used, mainly because of its wide range of applications and its wide application in nonlinear or time-varying control processes. The three parameters Kd, Kp and Ki in the PID controller are easy to set. They are the simplest and sometimes [sensitive words] controllers. Based on the development process of barrel temperature PID controller, from linear PID controller to nonlinear PID controller to PID controller based on BP neural network, this article explains the advantages and disadvantages of various controllers.
