Rotor Oscillation Damping of a Stepping Motor by Sliding Mode Control

摘要

Stepping motors are used mainly in OA and FA systems due to the merit of their digital driving behavior using switching devices. They are driven by closed-loop control in the systems where special performance such as prevention of out of synchronism or high- Speed drive is required. It is well known that rotor oscillation is one of the principal problems in switched drive of a stepping motor, nowadays several methods for damping of oscillation in which switching sequence is changed in respective manners have been suggested
