摘要： Common Aero Vehicle (CAV) is a hypersonic reentry platform which was developed in Falcon program. In order to guide CAV safely from initial reentry point to terminal area energy management (TAEM) interface, an improved real-time guidance algorithm including generating a reliable trajectory and tracking the trajectory is proposed in this work. Moreover, a multi-planning algorithm which can improve the guidance accuracy is applied in the guidance. Firstly, based on the well-known quasi-equilibrium glide condition (QEGC), a dynamic adjustment method for angle of attack is proposed to avoid the large phugoid oscillation in altitude. Then, the trajectory tracking controller meeting the real-time and robust requirements is designed based on linear quadratic regulator (LQR) theory. The Monte Carlo simulations are presented to demonstrate the capability and effectiveness of the guidance algorithm. ? 2017, American Institute of Aeronautics and Astronautics. All rights reserved.
