CONTROL ALLOCATION WITH ADAPTIVE FAILURE CONTROL

In the age of modern aircraft and fly-by-wire control systems, the inclusion of mechanical backup systems for handling instances of control failures is becoming more uncommon. As a result, pilots are forced to fully rely on the failure immunities designed into these systems and be assured that, should such failures occur, the aircraft maintain adequate flying qualities long enough for a safe ejection or an emergency landing. This paper demonstrates the control reconfiguration aspects of a control allocation with rate limiting algorithm to adapt to various control failures while still achieving desired moments, thus providing a safe environment for the pilot.
