Control Analysis of Magnetic Levitation System

Control system possesses lot of research effort towards the control of a Magnetic Levitation System (MLS). The control of MLS has the extensive scientific interest because of the highly nonlinear and unstable features thus make the modeling and control problems very challenging. The system eliminates friction, generates high-precision positioning and lessens maintenance cost. These merits make the system a good choice for applications like high-speed trains, magnetic bearings wind tunnel levitation and vibration isolation systems, etc. Several dynamic models of the system have been proposed and for these models various control strategies have been used and comparing their performance. This paper generates the methods of control technologies implemented on the magnetic levitation system.
