In contrast to conventional flux-weakening control methods, an algorithm based on operation times (T0) of zero voltage space vector for permanent magnet synchronous motor (PMSM) 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,...
This paper proposes a novel flux-weakening control algorithm of an interior permanent magnet synchronous motor for 'quasi' six-step operation. The proposed method is composed of a feed forward and a feedback path. The feedforward path consists of 1-dimensional look-up table, and the feedback is based on the difference between the reference voltage updated by current regulator and the output voltage...
