Prognostic and health management for aircraft electrical power supply system

According to the electrical power supply system analysis, a system of prognostic and health management (PHM) for the electrical power supply system is presented. The PHM system can accomplish the condition assessment of the key characteristics and device in the electrical power supply system without additional test equipment. The condition of rotating rectifier, contact resistance and so on can be evaluated by the data-driven approach. The architecture of the PHM system is easy to modify and update on the base of traditional aircraft electrical power supply system.
