| 研究実績の概要 |
This research targets at permanent magnet motor drive systems of 1~3MW/15000~35000rpm class, and study control method of high-speed permanent magnet direct-drive systems and magnetic bearing.
Based on the investigation of the current development state of theory and technology of the MW-level, we summarized the characteristics and problems in the field of high-speed permanent magnet direct drive system. Also, we started researching on the theory of high-speed permanent magnet drive system based on magnetic suspension bearing technology.
In particular, we submitted a journal paper presenting a new method of reconstructing current sensor faults and unknown disturbance for the closed-loop torque control system of an interior permanent magnet synchronous motor (PMSM). We conducted simulations and experiments to demonstrate the validity and effectiveness of the proposed method. Details will be available when the paper is published.
