Abstract
A method of controlling a motor controlled by a motor controller that includes a complex vector flux regulator (CVλR). The method includes: receiving at a field weakening regulator of the motor controller a modulation index that is a scaled version of an available voltage available to be provided to the motor by a voltage source; comparing the modulation index to a feedback modulation index to produce an error scalar that has a magnitude in a flux domain; determining a final direction (αfinal) of the error scalar in the flux domain; and providing the CVλR with flux commands in the d and q domain based on the error scalar and the direction.
