Design of Non-Linear Sliding Mode Controller for Magnetic Levitation System

This paper presents the design and implementation of Nonlinear sliding mode controller for the position control of the ferromagnetic ball in magnetic levitation system. The Nonlinear model has been designed using electrical and mechanical parameters of magnetic levitation system. This controller is with-stand against uncertainties in taken nonlinear system parameters and for the achieving the stability. Nonlinear sliding mode controller attenuate control input chattering also robustness against parametric uncertainties.
