Magnetic Levitation System (MLS) has been receiving increasing attention in recent years. It has numerous practical applications in many practical engineering systems such as high speed maglev trains which are being used in Japan and Germany, frictionless bearings, vibration isolation of sensitive machinery, levitation of wind tunnel models, aerospace shuttles, etc.MLS controls the magnetic field generated by an electromagnet to levitate a ferromagnetic ball in midair. With an appropriate controller in the loop, the small magnet levitates in the air indefinitely without any disturbance. Its...
