On two control methods for smoothing the linear tubular switched reluctance stepping motor position

This paper presents two control strategies proposed for the elimination of the oscillations of a linear tubular switched reluctance stepping motor. The first technique is the Bang Bang control mode which is an open loop control mode. The second solution is a fuzzy logic controller which has as inputs the back EMF voltages and its variations. So the major advantage of the designed FLC is that it does not use a position sensor which is cumbersome and very expensive.
