This paper reports on the modeling and control of a flywheel energy storage system used for electric vehicle. First, by the experimental vibration analysis based on the rigid model with H-infinity control, it was found that the main cause of the flywheel rotor instability due to the influence of the first bending backward mode than that of gyroscopic effect. Subsequently, a flexible model was derived...
This paper presents the effect of losses on a radial active magnetic bearings (AMB), used in the long term flywheel energy storage (LTFES). The study does not take into account the losses due to power electronics and windage losses (due to the friction between external rotor surface and the air). Therefore, we restricted the loss computation to those of radial AMB only. To simplify this work, we focused...
