In contrast to conventional flux-weakening control methods, an algorithm based on operation times (T0) of zero voltage space vector of permanent magnet synchronous motor (PMSM) for hybrid electric vehicle (HEV) application is proposed. In this paper, the d-axis current (id) is derived from a fuzzy controller. The proposed strategy can achieve fast dynamic control performance as well as parameter insensitivity in the flux-weakening region. Otherwise, it can also reduce the current amplitude of stator compared with the conventional method.
