摘要
This paper presents a varied-voltage DC-link fed electric vehicle (EV) synchronous reluctance motor (SynRM) drive. The key motor parameters are estimated, and used to adaptively determine the commutation angle for loss minimization. As to the dynamic control, the robust current and robust speed model following control schemes are pro-posed. To enhance the SynRM driving performance over wide speed range, a battery bidirectional interface boost-buck DC-DC converter is equipped to establish the speed-dependent varied DC-link voltage. For yielding quick voltage tracking and load disturbance regulation responses, a robust two-degree-of-freedom control (R2DOFC) scheme is proposed. The coordinated control between motor drive and interface converter is made. The driving performances of the whole EV SynRM drive by the proposed control are evaluated experimentally. In addition, the energy saving effectiveness is veri-fied. © 2021, Chinese Institute of Electrical Engineering. All rights reserved.
