Nonlinear Control of a Vertical Rotor Orientation System

Abstract

The rotor position control is the core issue of the active magnetic bearing (AMB) control. Aiming to the rotor position control during the rotor spinning launching period, this paper presents a nonlinear control approach based on the feed-back linearization technique. Theoretical derivation and simulation results are provided to illustrate the feasibility of this approach. The work in this paper may provide new thought of the vertical rotor position control problem.
