  "textContent": "A method for controlling operation of a torque-assist motor includes determining a rotational position of the torque-assist motor and producing a motor speed signal that is indicative of a rotational speed of the motor. One or more gain factors are produced based on the rotational speed of the torque-assist motor. An electrical current applied to the torque-assist motor is detected, and a current error is calculated based on a commanded electrical current and the electrical current applied to the torque-assist motor. A quadrature axis voltage is calculated based on the current error and the one or more gain factors. An inverter is driven with a direct voltage signal that is phased with the rotational position of the torque-assist motor so as to produce the electrical current applied to the torque-assist motor. The electrical current exhibits a characteristic that is affected by the quadrature axis voltage.",
