AbstractThe objective of this effort is to demonstrate a superior prototype diagnostic system and controller for electrical power systems based on AbTech's abductive polynomial network technology. This technology enables designers to semi-automatically model the complex and dynamic behavior of very sophisticated aerospace power systems using models comprised of a network of polynomial equations (abductive polynomial network). These networks offer the potential to: * increase fault detection and isolation beyond that provided by conventional built-in test (BIT) * verify sensor readings and isolate sensor failures * estimate system degradation * predict failures * enhance system control for a variety of operating and failure conditions This proposal introduces abductive modeling and AIM--a practical supervised learning tool for synthesizing abductive polynomial networks from databases of examples. It then discusses how abductive networks can be applied to substantially increase system control and diagnostic capabilities, and presents a demonstration project to apply abductive polynomial networks to electrical power system diagnostics and control.
