Enhancement of Lifespan and Operating Reliability Using a New Intelligent Control Method

Abstract:- This paper presents a bounce-duration reduction method for electromagnetic contactor systems. It combines the experience-based fuzzy algorithm and the hysteresis comparator with simple structure to form a newly fuzzy-hysteresis methodology, which is a valuable for minimizing the bounce duration after contacts closing. The proposed method is implemented in a microcontroller program with a specially designed data structure for obtaining the dynamic spring anti-force and the upper and lower force error limitations of the hysteresis comparator. Tests on the experimental prototype show that the newly proposed method is valid and fast in practical applications
