Simulating Research on Fuzzy PID Control to Synchronous Closing Operation of Permanent-Magnet Vacuum Circuit Breaker

摘要

As the impact of external factors, the operating time of the moving contacts of permanent-magnet vacuum circuit breakers would be variant. To implement desired motion behaviors of moving contacts, in this paper, a fuzzy PID controller was designed and simulated. The simulating results show that this controller can work efficiently in the course of synchronous closing though parameters varying, and prove its high precision and adaptability.
