Abstract
A field weakening control system for use with an induction motor is disclosed. The field weakening control system has a sensing device configured to generate a signal indicative of a speed of the induction motor and a controller. The controller is configured to determine an initial voltage command based on the signal and determine an acceleration of the induction motor based on the signal. The controller is also configured to generate a desired voltage command based on at least one of the initial voltage command and the acceleration.
