A Study for Controller Design Using 2-Degree of Freedom(DOF) Structure In A Magnetically Suspended System

자기부상시스템의 2-DOF 구조를 이용한 제어기 설계에 관한 연구

This study deals with the problem of balance beam system to stabilize about static and sinusoidal disturbance. wherein the design objectives are to keep the gap deviation from static and sinusoidal disturbance. In this paper propose the 2-Degree of Freedom(DOF) structure and a simple first-order controller which is designed by Characteristic ratio assignment (CRA) method. Matlab simulation result verify stabilization of balance beam system despite of disturbance. Hybrid simulation between digital controller and analog plant is presented by Matlab Simulink.
