Advance guidance and control utilizes control reconfiguration, guidance adaptation, trajectory reshaping, and an on-line mission/abort planner to achieve the best possible mission given that the vehicle's performance has been degraded by some sort of failure. Potential failures include actuator loss (locked, floating), engine out, damage to the vehicle, aerodynamic mismodelling, and so on. The trend towards the development of autonomous vehicles has placed more emphasis on requiring trajectory retargeting algorithms. One of the main difficulties of trajectory retargeting is predicting the effects of failures at future flight conditions. In this work, a method is presented that can generate critical information that is required to perform on-line trajectory retargeting.
