Method to Reduce Stepping Motor Vibration Using Type-2 Pre-compensator

Abstract

In this paper, we propose a novel method to reduce the rotor vibration of a stepping motor driven by a microstep driver. A low-pass-filter-type pre-compensator with the structure of a type-2 closed-loop control system is used to make it possible to eliminate the control lag in constant-speed tracking. The proposed approach enables the systematic design of a pre-compensator in the frequency domain. An experiment was performed to prove the effectiveness of the present method.
