Automated health monitoring and fault diagnosis in complex dynamical systems-- theory and applications

The proposed research is concerned with the study of fundamental research problems that would pave the way for designing the next generation of engineering systems that integrate conventional control system design with Fault Detection, Isolation, Estimation, and Accommodation (FDIEA) objectives, thus enabling the system to function for extended periods of time, safely, efficiently, with more autonomy, and less interruption in service. FDIEA problem is of crucial importance in safety and mission critical domains such as space and aerospace applications. In certain other domains, such as chemical/petrochemical, manufacturing, power and communication networks, safety to some extent, but mainly economics is the main motivation for having such capabilities. Yet environmental concerns and the desire for fuel efficiency drive the governments requirement for new vehicles to have On-Board engine Diagnostics capabilities (OBD II).
