Abstract :
A flywheel energy storage system is developed. The structure and dynamics characteristic of the system are discussed. The system consists of a disk-shaped rotor, active magnetic bearing (AMB), PID controller, displacement sensor and cabinet, etc. The rotor is suspended by three active magnetic bearings (AMB). A mathematical model of the system is derived and each degree of freedom motion is treated separately for the control system. PID control is applied to the AMB. The experiments have been carried out to measure the dynamic response of the rotor to direct disturbance. The results indicate that the fuzzy PID controller possesses good performance.
