| Outline of Final Research Achievements |
In this study, a new feedback type flux-weakening control method for current control of interior permanent magnet synchronous motors using values of voltage saturation, which is the difference between the output value of the auto current regulator (ACR) and the actual output value, and voltage margin, which is the difference between the output value of the ACR and its limit value, has been proposed. In the proposed method, the current and the torque responses can be improved because the current reference in the transient state can be designed by using values of voltage saturation and voltage margin. In addition, motor parameters are not used directly in the proposed method; therefore, this method has robustness to parameter variation. Simulation and experimental results were presented to demonstrate the effectiveness of the proposed method.
