Abstract
For high frequency injection (HFI) transition disturbance elimination, a processor directs an HFI transition for a motor. The processor determines compensation pulse voltages for an HFI compensation pulse. The processor further injects a sum of the HFI compensation pulse and an HFI voltage into a current regulator voltage output signal for a compensation Pulse Width Modulation (PWM) cycle. The HFI compensation pulse settles an HFI current to a steady state.
