论文摘要
研究了遇到两个拦截器的高超音速滑行车辆（HGV）的穿透轨迹优化问题。考虑到终端目标区域的HGV渗透轨迹优化问题，将其作为非凸的最佳控制问题。非convex最佳控制问题转化为二阶锥度编程（SOCP）问题，可以通过最新的内点方法来解决。此外，提出了仅提出拦截器的初始视线角度信息的穿透策略。通过提出的方法获得的收敛轨迹使HGV能够逃避两个拦截器并成功地到达目标区域。此外，提出了一种具有可变信任区域的SOCP方法，这对于平衡时间消耗和最佳性之间的权衡至关重要。最后，通过数值模拟验证了所提出方法的有效性和性能。
The penetration trajectory optimization problem for the hypersonic gliding vehicle (HGV) encountering two interceptors is investigated. The HGV penetration trajectory optimization problem considering the terminal target area is formulated as a nonconvex optimal control problem. The nonconvex optimal control problem is transformed into a second-order cone programming (SOCP) problem, which can be solved by state-of-the-art interior-point methods. In addition, a penetration strategy that only requires the initial line-of-sight angle information of the interceptors is proposed. The convergent trajectory obtained by the proposed method allows the HGV to evade two interceptors and reach the target area successfully. Furthermore, a successive SOCP method with a variable trust region is presented, which is critical to balancing the trade-off between time consumption and optimality. Finally, the effectiveness and performance of the proposed method are verified by numerical simulations.
