Research on Voltage Stabilizing System of Switched Reluctance Motor Based on Fuzzy PID Control

This paper proposes a control strategy based on fuzzy PID control of Switched Reluctance Motor Generator (SRMG) in response to the voltage fluctuation issues caused by load variations in switched reluctance motor system. This strategy is constructed based on the fundamental principles of closed-loop control and fuzzy control theory, incorporating a parameter-adaptive fuzzy PID controller and system model. Initially, a switched reluctance motor system was constructed to obtain voltage fluctuation data. Subsequently, aiming for voltage stabilization, a control algorithm for SRMG under constant speed mode was designed using the fuzzy PID controller, adopting a dual closed-loop control strategy for speed and current. Finally, compared with conventional PID control, the fuzzy PID controller was shown to effectively improve response speed, reduce voltage overshoot, and decrease voltage fluctuation time, demonstrating superior voltage stabilization performance.
