Abstract :
Secondary feedback is used in the ON-OFF control of electric heating to reduce the cycling time, but usually the secondary feedback loop is incorrectly designed and the droop error results. New concepts and techniques are introduced for analyzing the dynamics of a secondary feedback loop, and new design criteria are derived whereby the benefits of secondary feedback can be obtained without incurring the droop penalty.
