Design of H∞ controller for hybrid electromagnetic levitation system

Abstract

The present research findings regarding the designing controllers for hybrid electromagnetic systems are limited to optimal working conditions, which is hard to fit with the realworld applications where systems encounter various disturbances and uncertainties. To address these challenges, a H∞ robust controller has been successfully designed for a system consisting of a Hybrid Electromagnet (HEM) which performs disturbance rejection and deals with model uncertainties.
