This paper presents a co-simulation based methodology combining Finite Element Analysis (FEA) with time domain analysis aimed at the performance evaluation of sensorless control strategies for AC motor drives. In the paper the tool is used to compare various sensorless techniques, based on additional high frequency injection signals, implemented on an Interior Permanent Magnet Synchronous Machine...
This paper presents high frequency region position sensor-less vector control of permanent magnet synchronous motor (PMSM) drives. The proposed method enables to estimate pole position at high speed and reduce harmonic current. The proposed method estimates flux from a full order observer and estimates pole position with estimated flux. To improve the current waveforms inductances are added to the...
