摘要
结合我国运载火箭发展,梳理了传统制导方法的工程应用历程;针对故障适应性和自主化需求,分析了基于在线轨迹规划的制导方法发展概况。基于伪谱离散和凸优化理论,提出一套适应不同目标轨道的弹道轨道联合在线重构算法框架,并利用在线重构设计一种运载火箭故障导致推力不足后的自适应制导算法,通过数值实验和嵌入式测试,验证了在线重构算法和自适应制导方法的正确性、有效性。
The engineering applications of traditional guidance methods used in domestic launch vehicles are reviewed. In view of the requirements of fault adaptability and autonomy, the development of guidance methods based on online trajectory planning is analyzed. Based on the theories of pseudo-spectral discretization and convex optimization, a uniform algorithm framework for the trajectory-orbit-united online reconfiguration of different target orbits is proposed. An adaptive guidance algorithm is presented with the online reconfiguration for launch vehicle thrust faults. Finally, the validity and effectiveness of the proposed online reconfiguration algorithm and self-adaptive guidance method are verified by numerical experiments and embedded platform tests.
