The research of proportional integral differential(PID)method in the detection and control of temperature field,pressure field,velocity field and other process parameters in polymer injection molding process were reviewed,as well as the optimization of PID method in recent years.PID method could detect the processing errors and response to them in short time,and then further realize the effective controlling of process parameters.Using PID method to detect and control the processing parameters of polymer injection molding can effectively reduce the overshoot and steady-state errors of the parameters in the process of polymer injection molding,enhance the stability of processing,and produce polymer products with high quality and excellent performance.
