Different Controlling Methods And PIDController Design For Magnetic LevitationSystem

The main aspect in magnetic levitation systems are controlling the parameters by using the different controlling methods. Magnetic levitation system is used to levitate object by using attraction force or repulsive force between magnetic force and ferromagnetic material. The levitation of an object is possible using a control system to help stabilize the magnetic force. This report discussed on modelling and control of the magnetic levitation system. The magnetic suspension systems are based on maglev trains classified in two classes: electrodynamic suspension(EDS) and electromagnetic suspension(EMS it may be difficult to design a linear controller which gives satisfactory performance, stability, and disturbance rejection over a wide range of operating points. in this paper PID controller based on discontinuous mathematical model of the system for an electromagnetic suspension system which is applied in magnetic trains has been designed .
