Abstract—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 magnetic levitation forces exerted on a high-temperature superconducting hts disk by a cylindrical permanent magnet pm are calculated from ﬁrst principles for superconductors with ﬁnite thickness. The magnetic levitation system consists of an electromagnet, a metal sphere and an infra-red sphere position sensor the magnetic ball suspension system can be categorized into two systems: a mechanical system and an electrical system the.
Magnetic levitation (maglev) can create frictionless, efficient, far-out-sounding technologies here are some of the craziest uses that engineers and designers have dreamed up. Electromagnetic levitation-a useful tool in microgravity research julian szekely, elliot schwartz, and robert hyers electromagnetic levitation is one area of the electromagnetic processing of materials that has uses for both fundamental research magnetic levitation facility, the heat ca. Magnetic levitation has a very advanced and efficient technology we can use of it in industrial purpose as well as in office and homelike as the fan in buildings, transportation, weapon(gun, rocketry), nuclear reactor, use of elevator in civil.
Magnetic levitation is an advanced technology known as maglev in short in this magnetic forces lift, propel and guide a vehicle few centimeters above a guideway using magnetic forces the physical contact between vehicle and guideway is eliminated and permits cruising speeds in range of 500 km/h. Electromagnetic levitation is one area of the electromagnetic processing of materials that has uses for both fundamental research and practical applications this technique was successfully used on the space shuttle columbia during the spacelab iml-2 mission in july 1994 as a platform for accurately. Based on the viberation of bouncing,pitching and rolling directions,the vertical dynamics model of levitation chassis was established,and the equations of motion of the model.

Levitation: the state of rising and floating in the air in apparent defiance of gravity repulsion: the tendency of particles or bodies of the same electric charge or magnetic polarity to separate. Explore the latest articles, projects, and questions and answers in magnetic levitation, and find magnetic levitation experts. Although magnetic levitation has previously been used for macroscale objects, its use in life sciences has been hindered by the inability to levitate microscale objects and by the toxicity of metal salts previously applied for levitation. Maglev, or magnetic levitation, is a system of transportation that suspends, guides and propels vehicles, predominantly trains, using magnetic levitation trends in increased mobility of large masses with changing lifestyle for more comfort are leading to congestion on roads with automobiles.
Levitation which is the first part of this document and continues into do we really know how gravity actually works, a great study of information that seems to have been passed over throughout the ages or was it just covered up to distract the mind of humanity. Using planar magnetic levitation technology to move the platen perhaps among the most successful research in this direction is the one reported in (kim and trumper 1998), where the authors use a linear controller to actuate a 6 dof magnetic levitation device that achieves. Previous research at the university of adelaide and elsewhere has design for a magnetic levitation vibration isolator with a load-invariant resonance frequency is detailed through both quasi-static and dynamic modelling, and an experimental framework for testing the real prototype is outlined. Magnetic levitation is a technique or method by which an object is levitated or suspended and propelled using magnetism basically the magnetic forces.
