PHM and Principles of Diagnostics Conferences

NASA Ames and the Intelligent Systems Division had a strong showing at this year's Annual Conference of the Prognostics and Health Management (PHM) Society 2010 in Portland, Oregon on October 10-14. Members of Code TI presented technical papers and tutorials and chaired sessions. Kai Goebel chaired the Tutorial Sessions track. Abhinav Saxena presented the tutorial “Introduction to Prognostics,” and Guillaume Brat presentd the tutorial “Verification and Validation for PHM.” Jose Celaya was the session chair for “Anomaly Detection II,” and Bhaskar Saha was the session chair for “Machine Tool PHM III.” Over a dozen technical papers had contributions from members of Code TI. The Division also had an exhibitor booth at the conference showcasing Integrated Systems Health Management technologies, and Edward Balaban showed the Flyable Electromechanical Actuator (FLEA) testbed in hardware demonstration sessions.

Members of Code TI also participated in the 21st International Workshop on the Principles of Diagnosis co-located in Portland, Oregon on October 13-16. Scott Poll was the conference co-chair and Kai Goebel gave an invited talk on prognostics. Two papers and a poster were also presented. Data from the ADAPT Electrical Power System testbed in Code TI ias used in the 2nd International Diagnostics Competition held in conjunction with this conference.

Below is a listing of all of the technical papers and posters with Code TI contributions.

BACKGROUND: The annual conference of the Prognostics and Health Management (PHM) Society brings together the global community of PHM experts from industry, academia, and government from a range of application areas, including energy, aerospace, transportation, automotive, and industrial automation. The conference features workshops, town hall meetings, hands-on demonstrations, lectures, and tutorials.

The International Workshop on the Principles of Diagnosis is an annual event covering of a variety of theories, principles, and computational techniques for diagnosis, monitoring, testing, reconfiguration, fault-adaptive control, and repair of complex systems. Application of these theories, principles, and techniques to industry-related disciplines and other domains is a focus of the workshop. Researchers and practitioners from a range of backgrounds, including artificial intelligence, control theory, systems engineering, software engineering, and other related areas exchange ideas with others who share an interest in the different aspects of diagnosis and the related fields of testing, reconfiguration, maintenance, prognosis, and fault-adaptive control.
