A past project at NASA:

Hypersonics Guidance & Control
controls-oriented vehicle design of air-breathing hypersonic aircraft,
The research focus of the Hypersonics G&C project are:
- Development of models and associated control algorithms, analysis tools and design methodologies that permit the design of Highly Reliable Reusable Launch Systems (HRRLS) which offer robust dynamic performance in the presence of significant uncertainty by exploiting real-time measurements and available control actuators.
- Integration of control relevancy into the overall vehicle conceptualization, sizing, and design process. This will be done by incorporating control-relevant dynamical objectives (e.g. performance, robustness)
