Abstract:

A major problem in IPM motor drive during magnetic saturation is parameter mismatch between controller and motor model. This study aims to reduce mismatch by using 2-D inductance map. The 2-D map was determined by dq-axis current feedback, then applied to PI current controller and cross-coupling. Three scenarios were used to evaluate the effectiveness of the proposed method. The first two scenarios were neglect and consider saturation impact, respectively, under I_{d}^{*}=0A. The last scenario was by MTPA current controller with magnetic saturation being considered. This induction map was applied in PI current control and cross-coupling calculation between dq-axis. The key finding, the undershoot magnitude decreased by 66% during the transient under I_{d}^{*}=0 A. The JMAG simulation results confirmed the ineffectiveness of the PI current control occurs as parameter mismatch happened. The utilization of Ld and Ld map successfully reduces the mismatch and increases the robustness of PI current control.
