Abstract:
A Distributed, Autonomous, Coordination Architecture for Functionally Redundant Intelligent
Systems
Automation is critical to minimize human requirements for managing operations of
complex distributed networks such as the power management system for Space Station
Freedom. Intelligent systems are successfully automating individual control tasks
such as fault diagnosis and configuration management. However, further increases
in automation will require the development of autonomous control models that coordinate
heterogeneous, distributed operations support applications to work together cooperatively.
Functionally redundant systems represent an interesting problem. These systems provide
overlapping, complementary, or duplicate problem-solving capabilities, such as rule-based,
model-based, and neural network technologies, for fault diagnosis. Functionally redundant
systems offer opportunities for knowledge synthesis, hypothesis confirmation, and
fault-tolerant behavior. This effort will develop innovative group-based models and
neural network technologies for fault diagnosis. Functionally redundant systems offer
opportunities for knowledge synthesis, hypothesis confirmation, and fault-tolerant
behavior. This effort will develop innovative group-based models for autonomous coordination
to achieve these synergistic benefits. Specific goals will be to investigate generalized
interaction models for competitive, consensual, cooperative, and duplicate activities;
and to design an autonomous control architecture that unifies and applies these interaction
models to coordinate functionally redundant, heterogeneous, distributed intelligent
systems. These advanced control capabilities will enable NASA to increase automation
and safety in both space-based systems and ground control centers.
Intelligent distributed control architectures are broadly applicable to operations
and decision support for complex communication, computer, power and transportation
networks, and for process control in manufacturing and office automation domains.
