Robust active magnetic dearing control using stabilizing dynamical compensators

By G. R. Duan, Z. Y. Wu, Chris Bingham and D. Howe

Abstract

The robust control of active magnetic bearings, based on a linearised interval model, is considered. Through robust stability analysis, all the first-order robust stabilizing dynamical compensators for the interval system are obtained. Disturbance attenuation and minimum control effort are also addressed. The approach is applied to a high-speed flywheel supported by two active and two passive magnetic bearings. Simulation and experimental results both show that it is simple, effective, and robust
