Position/speed Sensorless Control for Permanent-magnet Synchronous Machines

On Position Sensorless Control for Permanent Magnet Synchronous Motor Based on a New Sliding Mode Observer

For the problems of buffeting and phase delay in traditional rotor detection in sensorless vector control of permanent magnet synchronous motor (PMSM), the Sigmoid function is proposed to replace sign function and the approach of piecewise linearization is proposed to compensate phase delay. To the problem that the output of traditional low pass filter contains high-order harmonic, two-stage fi...

Digital Control of Permanent Magnet Synchronous Motors

Permanent Magnet Synchronous Motor (PMSM) variable-speed drive is widely used in the industry because of its particularly high mechanical power density, simplicity and cost effectiveness. Eliminating the mechanical sensor mounted on the shaft of the motors gives further improvement. These drives are referred to as “sensorless” electrical drives. In this paper a novel sensorless algorithm is pro...
