Title:
METHOD FOR CONTROLLING PRIMARY MAGNETIC FLUX
Document Type and Number:
WIPO Patent Application WO/2014/069188
Kind Code:
A1
Abstract:
Provided is a technique for driving a rotating electrical machine at an efficient operation point in accordance with a torque by appropriately controlling the current phase with a primary magnetic flux command value modified in accordance with the torque in a primary magnetic flux control. When an amplitude Λδ of a primary magnetic flux adopts a value λδ0 (T) for a torque T, the amplitude ia of an armature current is set to the minimum value. At this time, a maximum torque/current control can be performed. Therefore, an armature current may be automatically determined by controlling the primary magnetic flux with the value λδ0 (T) adopted as the amplitude of the primary magnetic flux command value. That is, a current phase β is uniquely determined. In short, the current phase β is controlled to be a desired phase in accordance with the torque T, and thus the rotating electrical machine can be driven at an efficient operation point in accordance with the torque.
