Model and Control of Energy Storage Flywheel System Used in an Electric Vehicle

This paper is a report of the research of an energy storage flywheel system with a flexible rotor used for an electric vehicle. After introduce the energy storage flywheel system, the parameters of the rotor and the flywheel are decided by the vibration analysis of ANSYS. Based on the vibration analysis results, the model of the rotor and the flywheel is designed. In order to reduce the noise from ground, a moveable foundation is designed. Then robust controllers of the rotor system and the foundation are constructed respectively to decrease the noise from the ground. Form the simulation results, we verified that the proposed model and the controller are effective for the energy storage flywheel system used in an electric vehicle.
