A loss minimization control method for IPMSM drive system based on improved gradient descent algorithm

This paper proposes a loss minimization control method based on improved gradient descent algorithm (GDA) for interior permanent magnet synchronous machine (IPMSM). Since the power of PMSM is derived from measured phase voltage and current, this independent iron model containing motor parameters. Meanwhile, it can guarantee stability system when entering searching period. Both maximum torque per ampere (MTPA) id=0 are carried out to validate effectiveness proposed method. The experimental results demonstrated verify approach.
