Description
Summary: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 scheme, the extended exponential control barrier function (EECBF) is constructed by incorporating extended states and robust terms to deal with time‐varying constraint boundaries and uncertainties simultaneously. An adaptive programming for optimal transient performance envelopes is conducted to make a trade‐off between safety and transient performance constraints. It is shown that the proposed scheme for HSVs can confine AOA to time‐varying safety boundaries in the presence of uncertainties while the velocity and height tracking errors can always maintain within the desired transient performance envelopes. Simulations and comparisons are provided to verify the effectiveness of our scheme.
