Abstract

The magnetic suspension system is a typical nonlinear system, and is unstable with external disturbance. We designed a nonlinear suspension controller on the basis of feedback linearization and extended state observer, and observed the external disturbance by the controller. We compensated the feedback linear system with the observed value. The simulation results prove that the controller can suppress the disturbance effectively.
