Study on the optimal driving pattern of a stepping motor (2nd report, experimental study)

This paper mainly describes experimental results on a feedforward compensation in a start up and a slow down process of a stepping motor. To reduce the residual vibration in damping process, the driving pattern in slow down is analyzed by applying a similar optimization procedure proposed in the previous paper. And it is demonstrated to eliminate perfectly the residual vibration by the compensation of a few steps in the slow down process. The validity and the reliability of the proposed optimal driving pattern are confirmed experimentally with respect to various numbers of compensated steps and wide range of driving speed.
