Speed Sensorless Control of Permanent Magnet Synchronous Motors in Mine Electric Locomotive Drive
This paper presents a novel sensorless control method of permanent magnet synchronous motors a low speed based on a high-frequency voltage signal injection. The approach superimposes a persistent HF voltage signal into the estimated d-axis to get the rotor position error angle-related signal by dete...
