"This thesis deals with the electromagnetic and dynamic analysis of the magnetically levitated system. A simple experiment illustrating the principles of electromagnetic suspension (EMS) is described simulation test results are given. A U-shaped hybrid maglev system made of steel and neodymium magnet (rare earth magnet) acting as a source of magnetic flux attracts the ferromagnetic body (Guideway). Levitation forces are created by a controllable magnetomotive. Finite element analysis has been done to determine the levitation forces and magnetic flux to be used for system modeling. This type of levitation is unstable without the feedback control therefore we use a robust controller to maintain the air gap between the body in motion and guideway. Various different controller design methods are evaluated for this nonlinear model and the results are compared. Sensorless detection of air gap length in the maglev system has also been investigated and formulations for various modes of operation are presented"--Abstract, page iii.
