Abstract:

       We designed a temperature measurement and control system for rubber production. We employed pulse  interference suppression average filtering approach based on average filtering and median filtering to process temperature data in a temperature data collection and processing module. We used an integral separation PID algorithm in its output. Experiment shows that the system has high stability, short temperature adjustment time,and a control accuracy of 0.5℃ for a temperature signal.
