Flux Weakening of PMSM for Enhancing Torque Tracking [PDF]
2018 European Control Conference (ECC), 2018 Permanent magnet synchronous motors associated to their drivers are subjected to both current and voltage saturations. Dealing with those limitations is the core of flux weakening problem which aims defining achievable operating conditions. In stark contrast with most of the literature focusing on the steady-state, this paper investigates how current ...
