Notes:
Melt temperature is a key variable of the injection molding process. The evaluation of different control strategies for the melt temperature was based on the process dynamics presented in Part I of this work. The controllers tested were: PID (proportional-integral-derivative) control of barrel temperatures, direct PID control of melt temperature, Dahlin control, and Smith Predictor control of melt temperature. The controllers were tuned by simulation studies and were evaluated by a comparison of performance indices. The controller responses obtained through experiments were evaluated by comparing the rise time, peak overshoot, damping, settling time, and control effort. Analyses were performed to ascertain the sensitivity characteristics of the controllers.
