In recent year, Magnetic Levitation (MagLev) system has become famous and widely used in the high speed applications such as MagLev train, magnetic bearing, energy storage flywheel and vibration isolation of sensitive machinery. The MagLev system is contactless and frictionless, thus capable of reducing the noise and significant components wear and tear. However, it is a very challenging task to control the MagLev system due to its highly nonlinear characteristics and instability.
Classical controller such as PID controller are widely used in the industrial applications due to its simplicity and easy to design. However, the PID controller has a limited performance in positioning control of the MagLev system. In this research, a high-speed tracking controller is proposed to enhance the positioning performance of the MagLev system.
