Abstract
A method for controlling a motor is provided. The motor control method includes deriving a motor rotational speed estimate using a speed estimator model and deriving a motor hall sensor frequency estimate based on the derived rotational speed estimate. Additionally, a filter for noise detection is set based on the derived hall sensor frequency estimate and the derived rotational speed estimate. A motor hall sensor frequency derived from the hall sensor is then applied to a predetermined filter to detect a hall sensor noise frequency.
