Position/speed Sensorless Control for Permanent-magnet Synchronous Machines

comparison of conventional salient-pole synchronous generators and permanent-magnet-assisted salient-pole synchronous generators based on finite element analysis

this paper presents a novel salient pole synchronous generator i.e. permanentmagnet-assisted salient-pole synchronous generator (pma-sgs). due to saturationof conventional synchronous generators (sgs), permanent-magnet-assisted salientpolesynchronous generators (pma-sgs) are presented. pma-sgs are a new type ofsalient-pole synchronous machines with extra permanent magnets (pms) betweenthe adjac...

Sensorless position control of Permanent Magnet Synchronous Machines without Limitation at Zero Speed

Sensorless position control of Surface Mounted Permanent Magnet Synchronous Machines (SMPMSM) still is a challenge. High performance position control at low and zero speed is only possible using anisotropic effects being not considered in the fundamental-frequency machine models but in extended highfrequency models. This paper presents a new highfrequency injection method estimating the rotor p...

Rotor Position and Velocity Estimation for a Salient-Pole Permanent Magnet Synchronous Machine at Standstill and High Speeds

This paper addresses self-sensing (“sensorless”) control of salient-pole permanent magnet synchronous motors (PMSM’s). The major contribution of this work is the introduction of a simple-to-implement estimation technique that operates over a wide speed range, including zero speed. The technique achieves simplicity by decoupling the inherent cross-coupling in PMSM’s. The technique utilizes the d...

MRAS Based Sensorless Control of Permanent Magnet Synchronous Motor

Speed and torque controls of permanent magnet synchronous motors are usually attained by the application of position and speed sensors. However, speed and position sensors require the additional mounting space, reduce the reliability in harsh environments and increase the cost of a motor. Therefore, many studies have been performed for the elimination of speed and position sensors. This paper i...
