Abstract :
This paper discusses a prototype of miniature flywheel energy storage system. The system consists of a rotor with a flywheel disk and a pair of hybrid magnetic bearings (HMBs). The HMB is composed of both superconducting magnetic bearings (SMBs) and active magnetic bearings (AMBs). An H-infinity control method and zero bias method are applied to the AMB. In this paper, the design and dynamics of the flywheel energy storage system are discussed
