摘要：

This paper investigates the optimal trajectory and the feedback linearization control of a re-entry vehicle during TAEM (terminal area energy management) phase. First, an optimization algorithm with dynamic pressure as the cost function is used to obtain the optimal trajectory in TAEM. This optimal trajectory is considered the reference for ensuring a stable flight path of the re-entry vehicle. The control inputs are the angle of attack and bank angle, which determine the total energy and safety of the re-entry vehicle. Second, feedback linearization is used to design a tracking law in the TAEM phase. This paper validates the optimal solution as the reference trajectory with HAC (heading alignment cylinder) and the tracking performance of the re-entry vehicle onto the reference trajectory by feedback linearization.
