Fault Diagnosis and Fault Tolerant Control Research of a Flywheel Energy Storage System-a Survey

The basic working principle of a Flywheel Energy Storage System (FESS) is introduced. From the angle of failure detection means and fault types, the status and deficiency of the research on FESS Fault Diagnosis (FD) and Fault Tolerant Control (FTC) are reviewed. Moreover, the FESS FD and FTC methods are analyzed in detail. Finally, the deficiency, research hotspot and development trends of FESS FD and FTC are discussed.
