Design of a Variable Structure Controller Based on the Force Estimator for a Single Active Magnetic Bearings Suspended Rotor System
This study proposes a variable structure controller with a force estimator for a single active magnetic bearing suspended rotor system to eliminate the vibration associated with unbalance of mass. The model of a single active magnetic bearing suspended rotor system is build and a displacement and unbalancing force estimator of the system is established. A variable structure controller is also established according to the estimated force to decrease the influence of the unbalance force and increase the robust of the system. The experimental results showed that thevariable structure controller based on the force estimator for a single active magnetic bearing suspended rotor system was established successfully and has good accuracy.
