Abstract :
This paper presents the scheme that improves the performance of magnetic levitation. Magnetic levitation is complicated and difficult to control due to nonlinear characteristics of gap and current. So, we propose the Zero power control scheme using Extended Luenberger Observer taking into consideration nonlinear characteristics of gap and current. Also, we verified it by comparing the experiments with simulation
