METHOD AND APPARATUS FOR CONTROL OF AN AC ELECTRIC MOTOR WITH FIELD WEAKENING |
摘要 |
A method and apparatus for control of an alternating current electric motor with field weakening, including setting a required operating point for a motor field voltage component as a function of a difference between actual and required motor field current components, and setting a required operating point for a motor torque voltage component as a function of a difference between actual and required motor torque current components. The method also includes setting a field weakening constituent for the required operating point for the motor field voltage component as a function of a difference between a required operating point and an available value of the motor torque voltage component and as a function of a difference between actual and required motor torque current components.
