By Badr Mansouri and Jérôme Piaton Magnetic Saturation Aids Flux-Weakening Control Using lookup tables based on a static method of identification for nonlinear permanentmagnet synchronous motors. OR A GIVEN POWER voltage, the usual fluxweakening control of permanent-magnet synchronous motors (PMSMs) is based on two independent current regulators to expand the speed range of linear PMSMs. Therefore, the magnetic saturation is not often taken into account in these control strategies. Many authors have worked on this topic in recent years, but questions remain about the optimization of the flux-weakening space. In this article, by taking into account the magnetic saturation, an Digital Object Identifier 10.1109/MELE.2017.2756024 Date of publication: 26 December 2017 2325-5987/17©2017IEEE IMAGE LICENSED BY INGRAM PUBLISHING F IEEE Elec trific ation Magazine / D EC EM BE R 2 0 1 7 53
