“…Here the control law is constructed stepwise in such a manner, that at each step one state of the system is stabilized according to Lyapunovs direct method. Experimental results have demonstrated, that a very good disturbance rejection can be achieved with such a method (Sivrioglu 2007).…”

This paper analyses two control strategies, linear and nonlinear, for a 5-axis magnetic suspension system built with two three pole combined radial and axial bearings. Therein soft magnetic composites (SMC) are used as iron core material to carry the required three-dimensional flux distribution. While the linear approach has been designed around the CLARKE-Transformation to stabilize the bearing, the nonlinear one is based on feedback linearization to achieve a stable system even in the case of minimal bias flux. The paper outlines the control strategies and the controller design. Both schemes are compared regarding command response, decoupling performance and stability margin based on experimental results in the time and the frequency domain.

“…Due to the fact that only the position of the rotor and the two current i 1 and i 2 of the corresponding coils are available for measurement, a speed observer is needed to estimate the rotor speed. In this research, the nonlinear observer proposed in [17] is utilized for speed estimation as followŝ…”

In this paper, an appropriate control strategy is proposed to handle the nonlinear dynamics ofan active magnetic bearing (AMB). The goal of the control design is to drive the AMB rotor to the origin with improved transient response. In order to achieve this task, back stepping control technique with a barrier Lyapunov function are employed to keep the tracking error trajectory inside a predefined zone to avoid possible mechanical contact between rotor and stator. Besides, a speed observer is also used since information about rotor speed is not always available. The stability of the closed-loop system is proven. The effectiveness of the proposed control strategy is verified by numerical simulations.

In this chapter, the author presents an electromagnetic levitation system for active magnetic bearing wheels. This system consists of a rotor, a shaft, a cover, and a base. The author derives a meaningful electromagnetic force by using the singular value decomposition. The author develops a control system using the proportional-integral-derivative controller to control the position of the rotor and regulate the two gimbal angles of the rotor. The author gives the numerical simulation and experimental results on the control of the electromagnetic levitation system.
