要約(英語): Direct torque control (DTC), one of the known PMSM drive systems, can realize maximum torque-per-ampere (MTPA) control and flux-weakening control by yielding an optimal target magnetic flux. In this paper, an armature reaction flux control that can achieve MTPA control and flux weakening control is proposed for PMSM control systems using DTC. The proposed control focuses on the equivalence of the reactive power, which is an inner product of the stator magnetic flux vector and a current vector. In order to achieve MTPA control, the proposed control focuses on the rotor flux and current phase information and corrects the reference flux such that the rotor flux vector and current vector intersect each other orthogonally. Furthermore, flux weakening control is also achieved by correcting the reference flux in order to shift the current phase to produce the desired stator voltage. The effectiveness of the proposed control is experimentally confirmed.
