An optimal control approach for estimating aircraft command margins

This dissertation presents an optimal control framework to determine a collection of open-loop command signals, that mathematically guarantees operation of a dynamical system within prescribed state constraints. The framework is applied to estimate real-time command margins for aircraft control systems so that, safe operation within the flight envelope can be assured under appropriate control action. The margins are perceived as useful information to a pilot, especially during off-nominal conditions, as it can aid the pilot in avoiding flight envelope excursions, generally considered as causal factors to Loss-Of-Control incidents in aviation.Control & SimulationAerospace Engineerin
