| Abstract: | A temperature control system for plastic extruding machine based on Smith predicting balance theory is put forward, which adopts the PID control of the system temperature change, SCM(Single Chip Microprocessor) control technique, and the dual channel (heating/cooling)control method. The emulation results show that this temperature control system not only can overcome the effect of dead time on the stability of the control system and offer good robustness, but also is easy to operate with high precision. |
