Abstract: Sensors are widely deployed on high-speed trains for real-time operational status monitoring. The integrity of multi-sensor signals over time is critical for the train’s Prognostics and ...
Abstract: This article proposes a sensorless control method based on high-frequency (HF) voltage signal injection for permanent magnet synchronous motors (PMSMs) using multiple-branch sampling with a ...
