一种基于模糊逻辑的电压源逆变器感应电机驱动开路故障检测新方案

This article proposes a novel real-time fault diagnosis approach for open-switch faults of three-phase pulsewidth modulated voltage source inverter induction motor drive system. The diagnosis method relies only on the observed current via processing the extracted dc components and current absolutes using dynamic resonant filters (DRFs). By employing the ratio between the extracted dc components al...
