Abstract
A prognostic health and fault management system and method that accurately determines the health and rate of degradation of one or more flywheel systems, by comparing actual and simulated responses of flywheel systems to supplied command signals. Based on the determined health status and degradation rate of the flywheel systems, one or more unhealthy, active flywheel systems are deactivated, and one or more healthy, deactivated flywheel systems are activated. The system can be used in terrestrial applications, or in vehicles such as satellites, spacecraft, or ships.
