Sensorless Control of Permanent Magnet Synchronous Motor Based on Finite-Position-Set-Phase-Locked Loop

Research on PMSM sensorless control based on EKF

“…On the other hand, it reduces the reliability of the system and limits its' application potential in some complex environmental conditions at the same time. Therefore, many researchers have conducted indepth research on sensorless control technology and applied this technology to the control of permanent magnet synchronous motor [3][4].…”
