Backstepping Approach based Controller Design for Magnetic Levitation System

The magnetic levitation system has found very important applications in various industrial processes as well as in high speed transportation system. It has many advantages over the conventional wheel-on-rail transport. These advantages make it efficient in use instead of wheeled transport. The magnetic levitation system is highly unstable system. Therefore a controller is needed for its stabilization and control. The PID controller is successfully able to stabilize the system, but the transient response of the system is not up to the mark. In this paper, the author has implemented a Backstepping controller for the stabilization of the magnetic levitation system.
