Modeling and Simulation of Magnetic Levitation System

Overcoming the grip of the Earth's gravity has been a high-demand in current
technology. Through work of engineers and scientist, human has found many ways to
levitate a variety of objects to be applied in the field of mechanical and transportation.
Magnetic levitation (Maglev) is a way of using electromagnetic fields to levitate objects
without any contact with other material. However, magnetic levitation system is unstable
and non-linear. This paper presents the mathematical modeling of the magnetic
levitation system. Since magnetic levitation system is a non-linear system, it is
controlled using Proportional Integral Derivative (PID) controller and Fuzzy Logic
controller. The PID, Fuzzy Logic and Fuzzy-PID control techniques will be simulated
and compared to determine which one of them give the best control performance to the
system.
