This paper proposes a nonlinear control system to realize a zero power control of a energy storage flywheel system using magnetic bearings composed of electromagnets. It is assumed that the flywheel system has a rigid rotor in this paper. The nonlinear control system has been designed based on Lyapunov function, however, the condition of asymptotic stability derived from Lyapunov's direct method isn't satisfied. So the stability of flywheel system controlled by the proposed nonlinear control has been proved. The nonlinear control system switches the electromagnets depend on the displacement and the rotation of a rotor. It is clarified through the simulation that the proposed nonlinear control in this paper is a useful approach to realize a zero power control of a energy storage flywheel system.
