This paper describes results of a project to build a prototype expert system for automated fault isolation and correction of a regenerative CO2 removal device that is typical of functions of the air revitalization group in the Space Station environmental control and life support system (ECLSS). The software was developed using one of the powerful commercial knowledge engineering environments. The goal of the project was to evaluate the feasibility of using a software development environment to rapidly design, construct, test, and change expert system software. This paper discusses the use of expert systems to enhance automatic controllers, and the use of information on device design and on device troubleshooting and repair procedures in developing expert systems. This paper also describes the development of the prototype expert system and presents results of the evaluation.
