ABSTRACT:
Gauge inaccuracy due to hysteresis or lag during movement in one direction in response to a drive signal is overcome by predicting the amount of lag, which is a function of the desired amount of movement as measured from the farthest point attained during movement in the opposite direction, and adding the predicted lag to the drive signal.
