Abstract

An electric drive control apparatus including an electrically operated machine, a detector for detecting a current supplied to the electrically operated machine, and a controller that estimates a subsequent current based on a detected current, effects proportional operation processing based on an estimated current, effects integration operation processing based on the detected current, generates output signals based on a first value of the proportional operation processing and a second value of the integration operation processing, and generates an electric current to be fed to the electrically operated machine based on the output signals.
