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. |

DETAILED DESCRIPTION The present invention provides a prognostic health and fault management system and method for energy storage flywheel systems that accurately determines the health and rate of degradation of the flywheel system by monitoring the health and degradation rate of various systems and components within the flywheel system.
The prognostic health and fault management system also provides the capability to activate a deactivated spare flywheel system based on the determined health status of the active flywheel systems.
A satellite is also provided that includes the innovative system.
In one embodiment, and by way of example only, an energy storage and supply system includes one or more energy storage flywheels, one or more simulation models, and a prognostic controller.
Each of the energy storage flywheels is coupled to receive one or more flywheel command signals and is operable, in response thereto, to supply one or more actual flywheel response signals.
Each simulation model is of at least a portion of each energy storage flywheel.
Each simulation model is coupled to receive the one or more flywheel command signals and is operable, in response thereto, to supply one or more simulation model response signals.
The prognostic controller is coupled to receive one or more of the actual flywheel response signals and one or more of the simulation model response signals and is operable, in response thereto, to supply one or more signals to selectively activate and deactivate one or more of the energy storage flywheels.
In another exemplary embodiment, a method of monitoring the health of an energy storage and supply system having one or more energy storage flywheels includes supplying one or more flywheel commands to each of the energy storage flywheels and to a simulation model of at least a portion of each of the energy storage flywheels.
An actual response of each energy storage flywheel to each of the supplied commands is monitored, as is a simulated response of each simulation model to each of the supplied commands
