This chapter presents various concepts for integrating real-time vehicle health assessment and fault contingency management technologies for unmanned air vehicles. The presented integrated vehicle health management (IVHM) and automated contingency management (ACM) system architecture is shown to support real-time, onboard health state assessment and fault management so that UAVs can enjoy greater autonomy and survivability during anomalous operating conditions. Selected real-time system identification and automated health assessment algorithms are presented that can readily identify the dynamics and performance limitations of degraded UAV systems. Additionally, a high-level mission adaptation approach is presented to estimate the safe flight operating envelope after the occurrence of faults. Reconfigurable fault-tolerant control techniques that directly utilize the identified UAV subsystem dynamic models have been developed and tested in simulation. Finally, proof-of-concept demonstrations are presented using NASA engine and aircraft dynamic models with simulated engine and actuator faults. Simulation results and remarks on future work are also presented.
