NASA has undertaken the design of a manned space station. To decrease both airborne and ground support costs, subsystem designers are encouraged to automate activities ordinarily performed by humans. The Lewis Research Center has been charged with developing a highly automated system for generation, storage, and distribution of electrical energy aboard the Space Station. Conventional algorithms enhanced by expert systems are proposed for this task. An autonomous power system will require the intelligence to schedule power, allocate energy, diagnose failure causes, propose goals, prepare plans, evaluate consequences, and select the best plan for execution. Crew-interactive, expert systems can be ready for automating the initial space station, but complete system autonomy will need more development time.
