Abstract

The electromagnetic levitation system is a nonlinear system. The force applied by the electromagnet on the levitating magnet can be approximated a nonlinear model. The conventional controller with linearization of nonlinear systems design is presented without highly controlling performance enough. This paper is demonstrated the design of servo system using pole-placement with state observer for the magnetic levitation system from the equilibrium point. In addition, these closed-loop poles correspond to the desired closed-loop poles in the pole-placement approach and state observer estimate immeasurable state variables. Finally, the simulation and experimental results showed effective control objective.
