Abstract

This paper based on the background of PVC production process in the chemical plant, analyzes deeply the characteristics of PVC polymerization temperature and the difficulty of control. A new method of PID control based on Internal Model Control is proposed. Internal Model Control has a better control against time-delay and disturbance. Combining these two, we can control the polymerization temperature more accurate and stably. By the simulation, this method is shown to be effective and has better stability, robustness, capability against disturbance.
