  "textContent": "A system and method of operating a vehicle. The system includes an inverter, a motor, and a sensor for measuring a phase current between the inverter and the motor in a first phase cycle in which the inverter is operated at a first voltage. A processor predicts an observed phase current and a raw disturbance voltage for the second phase cycle from the phase current, calculates a damping voltage correction for the second phase cycle from the observed phase current and a disturbance voltage correction for the second phase cycle from the raw disturbance voltage, calculates a final voltage in the second phase cycle from a core current regulator voltage, the damping voltage correction and the disturbance voltage correction, calculates a second voltage in the first phase cycle by applying a delay to the final voltage in the second phase cycle; and applies the second voltage at the inverter.",
