Energy Saving Robust Control of Active Magnetic Bearings in Flywheel

Abstract: The paper reports on the investigation and development of the flywheel device as a energy storage system (FESS). The FESS is designed to operate in a vacuum and is supported on a low energy controlled active magnetic bearings (AMBs). The goal was to design and experimentally test the self integrated flywheel conception with a smart control of the flywheel rotor magnetic suspension. The low power control approach, with the reduced bias current, of the flywheel active magnetic bearings is used. The weighting functions are de-signed in order to meet robust control conditions. The laboratory investigations of the flywheel with high gyroscopic effect operated at low speed met the control and energy performances requirements.
