要約(英語): This paper describes a the position sensorless vector control system for PMSM in the inverter overmodulation drive. Operating PMSM in the inverter overmodulation range achieves a fast torque response and widens the high-speed drive region of PMSM. However, in the overmodulation range of the inverter, harmonics voltage/current affect not only the closed loop current control system but also the position/speed estimation system and then become unstable in the worst case. To solve this problem, the authors propose a position sensorless control system with harmonic estimator to compensate for the harmonics components.In this paper, focusing on the position estimator, the effectiveness of the proposed system is demonstrated by discussion about the problem of the conventional system and is evaluated by several experiments.This paper is organized as follows. First, the problems of the conventional position estimation methods in the overmodulation range are described. Next, two approaches for improving position estimation in the overmodulation range are compared. Lastly, the effectiveness of the proposed method is confirmed through several experiments.
