ABSTRACT:
A method and apparatus for essentially eliminating turn-on delay distortions in terminal voltages and currents in a three phase motor control system wherein a compensator provides correction voltages which are added to command voltages as a function of feedback current amplitudes. Also a method for calibrating an open loop turn-on delay compensator during a commissioning procedure using a closed loop current controller.
