Sensorless Speed Control of PMSM in Low-Speed by High Frequency Pulsating Injection with Double Modulation Error Compensation Ferdiansyah, Indra Hanamoto, Tsuyoshi 20669 花本, 剛士 30228514 7003982396 0000-0001-8836-6020 321 A novel improvement scheme for the High Frequency Pulsating Injection-Sinusoidal (HFPI-S) method that considers the error function is proposed and implemented for PMSM sensorless control. The limitations in extracting the error function and dealing with signal noise at low-speed could appear the estimation errors in rotor position within the HFPI-S system. In this study, a new model for the proposed method, including the addition of dual modulation as error compensation in the process of extracting rotor position and enhancing the observer for conventional rotor position signals was focused. The results of this study showed that the extraction of the error function that is expanded could obtain more accurate results. Therefore, the addition of dual modulation and the observer enhancement could be effectively applied to maintain the accuracy of rotor position estimation even under low-speed and loaded conditions. journal article EDP Sciences 2024-01-08 VoR application/pdf E3S Web of Conferences 473 04001 https://kyutech.repo.nii.ac.jp/record/2001387/files/10448703.pdf http://hdl.handle.net/10228/0002001387 https://kyutech.repo.nii.ac.jp/records/2001387 eng Copyright (c) The Authors, published by EDP Sciences, 2024.
