Control Strategy in the Flux Weakening Region of Interior Permanent Magnet Synchronous Machine Used in HEV

Abstract:

An new control strategy for interior permanent magnet synchronous machine (IPMSM) which is the most popular motor used in HEV is proposed and investigated, which features is increasing the reference flux weakening voltage to improve efficiency in flux weakening region . Modeling results show that the proposed strategy can achieve the same dynamic and steady state torque performance with higher reference flux weakening voltage, which means higher efficiency.
