A Control System of a Full-Step-Driven Stepping Motor with a Compensator for Rotor Oscillation Damping

Abstract

The authors present a new pre-compensator used for control of a stepping motor in the oscillation-damping type full-step drive system. The compensator is a low-pass filter, in which the cut-off frequency varies with reference speed variation, and is used for adjustment of reference angle waveform. The effect of this system for rotor oscillation damping is verified by the experiment.
