Active magnetic bearing control in 3D model

Abstract

The aim of this article is modeling, simulation, control and complex design of Active Magnetic Levitation Systems (AMLS). In this application is necessary to proposed the effective control law for the stable operation in levitation mode because these devices in nature are essentially unstable. The stabilizing controller has to generate the appropriate value of electromagnetic force to levitate an object. It is highly important to choose convenient form and parameters of the controllers. The design parameters and controller design should be analyzed in a complex form at the modeling stage. Magnetic levitation system for 3 and 5 axis model of magnetic bearing is analyzed, because AMLS are specific mechatronics devices where the construction and control laws are strongly joined. Simulation results of 3 and 5-axis model are presented to verify correct form and parameters of the proposed controller.
