A total power control technology on PID temperature controllers

Abstract

The heating equipment which are widely used in the industrial world consume a tremendous amount of electric power. For this reason a limit that is lower than the equipment's actual capacity is often set on power consumption in order to suit the company's power supply and equipment situation. This inevitably affects the equipment's heating performance. We have therefore developed a total power control technology which prevents the overall power consumption of a system of several PID temperature controllers from exceeding a preset limit, while at the same time maintaining a high level of tracking performance so that the temperature stays close to the set point.
