The search for new solutions of bearing systems in modern rotating machines that have to satisfy special performance demands has resulted in interest in rotor active magnetic suspension systems. The application of magnetic bearings as a system of shaft suspensions gives supplementary, unparalleled in classic solutions, diagnostic capabilities. New solutions in bearing systems have been more and more frequently applied in modern rotating machines. They include magnetic bearings that enable the active control of rotor vibrations. This paper presents an idea of programming a level of vibrations in the operating range of the rotating system of the flexible rotor (including critical speeds) by using an additional digitally controlled magnetic bearing. It causes a qualitative change in the dynamic properties of the system. Some experimental investigations and numerical simulations of flexible rotor dynamics carried out on the test stand with an additional, digitally controlled magnetic bearing are discussed.
