Abstract

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 (i_d) 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.
