First, a set of ascent trajectories is obtained as candidates for tracking control through a trajectory design method that considers the available acceleration.

The openloop dynamics of air-breathing hypersonic vehicles is responsible for these limits on the control system. Comprehensive specifications on stability, tracking accuracy, and robustness are derived, and the flight envelope with constraints and control specifications is identified.
