Diagnostics for active management of aircraft system failures

Describes development and analysis of a distributed failure detection and isolation system for commuter and business aircraft. We define several candidate failure scenarios (e.g., aircraft icing, failures of control surface actuators, stuck or floating control surfaces) that are both common occurrences and amenable to improved control solutions and construct a hybrid model, suitable for simulation studies. The development of an algorithm that can reliably detect and isolate system failures with minimal disruption of normal operations constitutes the heart of the paper.
