An electromagnetic levitation controller design considering guideway deflection is presented. Even though to design a maglev controller to make a vehicle steady suspension under guideway deflection is a key technology in maglev vehicle system, the vehicle-guideway interaction effects haven’t well explored and yet settled. Unlike most approaches based on the linear model, a maglev controller is ...

Hybrid-electromagnetic suspension (EMS) system is type that vehicle levitates from guide-way. An advantage of this system is no energy consumption at nominal operating point which is maintains levitation using attraction force by permanent magnetic only. The EMS system is inherently unstable. It means active control needs to be incorporated for stable levitation. And it needs control method whi...

This paper aims at development of non linear dynamic model for Magnetic Levitation System and proposed linear and nonlinear state space controllers. The linear controller was designed by linearizing the model around equilibrium point, while nonlinear controller was based on feedback linearization where a nonlinear state-space transformation is used to linearize the system exactly. Relative degr...

This paper deals with the control aspects of magnetic levitation system using fuzzy logic controller (FLC). The magnetic levitation system is a mechatronic system already acknowledged and accepted by the field experts. For such a system it is desired to proposed a suitable controller for positioning a metal sphere in air space by the help of an electromagnetic force. In the ideal situation, the...

Electromagnetic levitation (EML) enables the handling of samples in a containerless manner, facilitating more precise measurements or manipulation materials. Currently, EML coil design is based on two-dimensional (2D) mathematical models combined with empirical data and experience. We propose that employing truly 3D model accurate rational design. This approach shows significant differences mag...

The research in the present paper focuses on decoupling the six-degrees-of-freedom motions of a magnetically levitated stage with moving coils and controlling the levitation motion. The decoupling is based on commutation of coil array, which is obtained reversely from the electromagnetic force/torque model of the stage. The control of levitation motion is carried out by a phase lead-lag control...

|This paper presents a new TEAM workshop problem taking into account moving bodies. An electrodynamic levitation device which consists of a conducting plate over two exciting coils shall be examined. The aim is to determine the dynamic characteristics of the levitating plate. A coupled solution of the electromagnetic and the mechanical problem is necessary for that.

This paper deals with the present scenario of magnetic levitation with LIM. The magnetically levitated train has no wheels, but floats-or surfs-on an electromagnetic wave, enabling rides at 330 miles per hour. By employing no wheels, maglev eliminates the friction, and concomitant heat, associated with conventional wheel-on-rail train configurations. There are two basic types of non-contact Mag...
