Sensorless Direct Torque Control of Surface-Mounted Permanent Magnet Synchronous Motors with Nonlinear Kalman Filtering

Initial Rotor Position Estimation and Sensorless Direct Torque Control of Surface Mounted Permanent Magnet Synchronous Motors Considering Saturation Saliency

For a p ractical direct torque controlled (DTC) permanent magnet synchronous motor (PMSM) drive system, the information of the initial rotor position, which is usually obtained by a mechanical position sensor, is essential for starting under the full load. In order to avoid the disadvantages of using mechanical position sensors, great efforts have been made on the development of sensorless cont...

Parameter Identification of Permanent-magnet Synchronous Motors for Sensorless Control

An online parameter identification method is proposed for sensorless control for surface and interior permanent-magnet synchronous motors (SPMSMs and IPMSMs, respectively). As this method does not use rotor position or velocity to identify motor parameters, the identified parameters are not affected by position estimation error under sensorless control. The proposed method that is based on syst...
