The advent of highly efficient and superior digital devices and fast microprocessors for control application has opened the field of discrete time controller design. This paper presents an exciting application of magnetic levitation system using discrete sliding mode control. There is a limited volume of literature available for discrete sliding mode control as applied to magnetic levitation sy...

Magnetic levitation, which uses a magnetic field to suspend objects in a fluid, is a powerful and versatile technology. We develop a compact magnetic levitation platform compatible with a smart-phone to separate micro-objects and estimate the density of the sample based on its levitation height. A 3D printed attachment is mechanically installed over the existing camera unit of a smart-phone. Mi...

Since a power supply substation of the magnetic levitation train system includes an inverter which is necessary to change the frequency of power, it has a different characteristic comparing to any other railway system. Nowadays, a study is undergoing to determine rating of facilities constituting a power supply system and modeling that system. This paper proposes an analysis model for the power...

Magnetic levitation conveyor systems have many advantages compared with the general conveyor systems. Because of the non-contact structure, magnetic levitation systems offer frictionless, low noise, and the ability to operate in highly clean environment. In this environment, materials are sensitive to change location. When materials move to the desired position, the controller is required to be...

Magnetic levitation is an interesting phenomenon of lifting/ suspending objects without any physical contact using magnetic power, which finds multitude of applications in modern technologies. The objective of this article is to interactively demonstrate magnetic levitation using a simple experimental setup with intent to increase the efficacy of science and engineering pedagogy in teaching-lea...

This paper presents the design of feedback linearization and neural network based feedback linearization (NARMAL2) controller for a magnetic levitation system. The magnetic levitation system is one of the classical nonlinear systems. The paper provides simulation results to validate the theoretical design.

Magnetic levitation as a means of motion and force/torque control can provide many advantages for high-fidelity haptic interaction, as compared to motorized linkage and cable actuation. Impedance-based haptic interface devices function both as force display devices, generating forces and/or torques to be felt by the user, and as input devices, sensing the motions imparted by the user to the dev...

The dispersed particles of magnetorheological fluid form stable chain-like clusters under the magnetic field, and show an effect of controllable flowability and shape. Based on this characteristic, using migration magnetic acted on the magnetorheological fluid, the object directional migration can be realized, and then the magnetorheological fluid forms levitation at the same time, which has li...

KGaA, Weinheim (1 of 10) 1600144 wileyonlinelibrary.com based on their refractive index and size.[4] Label-free approaches eliminate the need for cell markers and allow separation based on intrinsic cell properties. Magnetic levitation enables label-free, sensitive, and specific density measurements of particles which are suspended in a paramagnetic medium and...

Several cellular events cause permanent or transient changes in inherent magnetic and density properties of cells. Characterizing these changes in cell populations is crucial to understand cellular heterogeneity in cancer, immune response, infectious diseases, drug resistance, and evolution. Although magnetic levitation has previously been used for macroscale objects, its use in life sciences h...
