【Abstract】 This paper presents the measure of direct torque control of induction motor using voltage space vector based on stator flux rotary coordinate system. Firstly, we establish coordinate system on stator flux track circularity′s tangent orientation, and the expect voltage space vector acquires several fixed voltage space vectors in this coordinate system, then the expect voltage space vector is mapped into radiate distributing chart of inverter′s voltage space vector, and the expect voltage space vector is generated by combination of the adjacent two voltage space vector. This method has the virtue of simple model and easy realization.更多还原
