Nonlinear Feedback Control of a Five Axes Active Magnetic Bearing

The demands on active magnetic bearings concerning performance as well as costs are high. The proposed five axes active magnetic bearing has a compact design and runs with simplified power electronics. Owing to the nonlinearity of the plant, the use of linear control design methods alone is not suitable for achieving a high operation performance. This paper introduces a novel combined radial and axial position control algorithm. Experimental results demonstrate the effectiveness of the proposed approach.
