A Digital Controller Design of Magnetically Suspended System

초록

Abstract: 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, we propose the 2-Degree of Freedom(DOF) structure and a simple first-order digital controller which is designed by Characteristic ratio assignment (CRA) method. Despite external disturbance, the result, simulated by Matlab, verifies stabilization of balance beam system. Hybrid simulation between digital controller and analog plant is presented by Matlab Simulink.
