Abstract

A system and method for controlling an AC motor drive includes a control system programmed with an algorithm configured to optimize operation of the motor drive. Specifically the control system is programmed to input an initial voltage frequency command to the drive. The initial voltage frequency command includes a voltage reference and a frequency reference corresponding to an operating point of an initial voltage/frequency (V/Hz) curve. The control system monitors a real time output of the drive modifies the voltage reference based on the real time output of the drive and transmits a modified voltage frequency command to the drive. The modified voltage frequency command corresponds to an operating point of a modified V/Hz curve defined by the modified voltage reference and the initial V/Hz curve.
