recommendations! Published in 2024 at "International Journal of Robust and Nonlinear Control"

DOI: 10.1002/rnc.7723

Abstract: This paper proposes an enhanced safety‐critical control scheme for hypersonic vehicles (HSVs) with multiple constraints, where both safety constraints (e.g., actuator saturations and time‐varying angle‐of‐attack [AOA] limitation) and transient performance constraints are considered. In this… read more here.
