The paper has describes the complete design and investigation processes of permanent magnetic bearing. The passive magnetic bearing (PMB) rotor suspension rig employing no active control components was calculated, designed, constructed and tested. In order to increase the radial passive magnetic bearing stiffness, the Halbach-array configuration was used. The main purpose of the work was develo...

This paper deals with an application of H∞ control attenuating initial-state uncertainties to the magnetic bearing and examines the H∞ control problem, which treats a mixed Disturbance and an Initial state uncertainty Attenuation (DIA) control. The mixed H∞ DIA problem supplies H∞ controls with good transients and assures H∞ controls of robustness against initial-state uncertainty. On the other...

The purpose of this paper is to present a new type of dynamic balancing system, having a driving solution of the rotating part based on magnetic interactions. The magnetic system also plays the role of an elastic bearing. In the first part of the article is presented the technical solution which allows the dynamic balancing evaluation depending on the radial displacement between two disks with ...
