摘要

The structure of switch table mode direct torque control (DTC) is simple, in which the stator flux space is divided into 6 regions. But traditional stator flux sector judgment is much more time-consuming due to the trigonometric calculations in the orthogonal stationary coordinates. A new method is proposed to make stator flux sector judgment which is implemented in 60 degrees coordinate system.
