With the requirement of high reliability and indemnificatory of on-board hydraulic power supply system, the general structure of prognostics and health management (PHM) of hydraulic power supply system based on its fault mechanism was presented, the function of every layer in PHM of hydraulic power supply was described, and the key technology of on-board PHM system and ground maintenance system was studied. Considering the rapid calculation requirement, the on-board PHM and ground database of maintenance based on digital signal processor was designed. Intelligent diagnosis algorithm and effective fault prognostics were realized. The correctness and validity of the structure of PHM of hydraulic power supply system were tested and verified though the experiments.
