Electromagnetic levitated and guided system is commonly used in the field of people transport, tool machines frictionless bearing and conveyor system. In the case of low speed people transport vehicles, the electromagnetic levitation offers the advantage of a very salient motion and of a reduced maintenance of the rail.In this work FEM based analysis and design of different structure of rail (g...

BACKGROUND Diamagnetic levitation is a technique that uses a strong, spatially varying magnetic field to simulate an altered gravity environment, as in space. In this study, using Streptomyces avermitilis as the test organism, we investigate whether changes in magnetic field and altered gravity induce changes in morphology and secondary metabolism. We find that a strong magnetic field (12T) inh...

BACKGROUND In aerodynamic levitation, solids and liquids are floated in a vertical gas stream. In combination with CO2-laser heating, containerless melting at high temperature of oxides and silicates is possible. We apply aerodynamic levitation to bulk rocks in preparation for microchemical analyses, and for evaporation and reduction experiments. RESULTS Liquid silicate droplets (~2 mm) were ...

This paper presents regulation and tracking control design for a magnetic levitation system (Maglev). First, the nonlinear dynamic model of magnetic levitation system was built. Second, a sliding mode control (SMC) is constructed to compensate the uncertainties occurring in the magnetic levitation system. The control gains were generated mainly by experimental method. Next, a composite controll...

INTRODUCTION Noncontact transfer devices are demanded when silicon wafers or glass plates are carried in clean environment. Because contact of such products with a conveyer belt damaged their surface, non-contact transfer devices are needed for the use in clean environment. Many transfer devices using ultrasonic, electromagnetic or electrostatic levitation have been proposed. The authors also h...

Swallowable capsule endoscopy is used for non-invasive diagnosis of some gastrointestinal (GI) organs. However, control over the position of the capsule is a major unresolved issue. This study presents a design for steering the capsule based on magnetic levitation. The levitation is stabilized with the aid of a computer-aided feedback control system and diamagnetism. Peristaltic and gravitation...

This thesis describes the design procedure, analysis, and control of a single actuator magnetic levitation system. First the details of the system design and construction are presented, followed by an analysis of the relevant sub-systems and controller theory. Experimental levitation data is collected and compared to the theory. Utilizing a lead-lag controller, the maglev system is made stable ...

Levitation drift in the high-Tc superconducting levitation systems is directly related to the safe operation of the systems. In these levitation systems, the gap between a superconductor and a permanent magnet may decrease, increase, or keep unvarying with time. Based on the numerical simulations of the magnetic force-gap hysteresis relations of two different physical processes in field cooling...

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...

In this paper technique applies is known as parallel distributed compensation (PDC). This PDC technique is used for the position control of a Magnetic Levitation system. Parallel Distributed Compensation technique is based on the TS-PDC type fuzzy model. In this paper it is shown that this PDC technique can be successfully used for the stabilization of Magnetic Levitation System at any arbitrar...
