Aimed at the typical nonlinearity characteristics of maglev system

an integral variable structure control(IVSC) is proposed.In this paper

a nonlinear dynamic mathematical model for the magnetic levitation system.With the principle of sliding mode control to design the controller

import an integral party in switch function is constructed

and the smooth and continuous saturation function is used to replace the sign function

and effectively undermine the system of steady-state error.Simulation results verify t...
