The different stages of charging, discharging, and monitoring a flywheel energy storage system''s energy storage capacity make up its operational process and performance. Here is a summary of a FESS''s performance requirements and operational process (Kenny et al., 2005 ).
A high rotating speed of the flywheel can increase the power capacity but it also increases the disturbance load torque on the FW rotor. An observation control model of load torque is therefore proposed to mitigate the disturbance load torque acting on magnetically suspended FESS (MS-FESS) during the charging process.

Flywheel energy storage works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy [30,31,32]. When energy is extracted from the flywheel, the flywheel''s rotational speed will reduce as a consequence of the principle of Conservation of Energy.
