Abstract
A device for implementing a method for predicting rotational positions of a rotating shaft is disclosed. A motor shaft is rotated over a range of rotation. The device detects each incremental rotation position of the motor shaft from a set of incremental rotational positions being spaced by a fixed increment. Prior to a change in the rotational speed of the motor shaft, the device generates a prediction of each rotational position. When a detected incremental rotation indicates a change in rotational speed of the motor shaft, the device modifies the prediction of each motor shaft position in a continuous manner.
