Design of guidance law for hypersonic drone based on trajectory profile

In this paper, longitudinal and transverse lateral guidance methods are proposed to solve the trajectory tracking problem of hypersonic drone during the return of the energy management segment. A three-degree-of-freedom particle model of a hypersonic drone was established, and the longitudinal and transverse lateral guidance laws were designed to guide the drone to track the longitudinal and transverse trajectory profiles, so that it could reach the landing window with the desired energy state. Finally, the three-degree-of-freedom model is used to simulate and analyze the guidance law.
