An improved maximum torque per amp control strategy for induction machine drives

In this paper, an improved maximum torque per amp control strategy for induction machine drives is proposed. The proposed control strategy is simple in structure and includes the effects of magnetizing and leakage saturation. It is experimentally shown that the proposed control strategy produces the desired torque with the minimum stator current for the entire torque range and that this control strategy yields superior performance over a control strategy based on the classical qd induction machine model
