摘要:
针对高超声速滑翔飞行器多约束条件下的再入段制导问题,文章提出了一种基于在线轨迹优化和最优反馈控制的闭环最优反馈制导方法。建立了再入段制导问题的复杂多约束数学模型;设计了一种能有效处理内点约束和分解复杂终端约束并考虑在线自主避障和适应目标变更需求的制导策略;进而结合基于Radau伪谱法和序列二次规划算法的在线轨迹优化方法和基于采样保持反馈控制的最优反馈控制的思想,提出了再入段闭环最优反馈制导方法。数值仿真结果表明,该制导方法具有良好的自主制导能力,并且能满足在线解算最优制导指令的实时性要求。
Abstract:
A closed-loop optimal feedback guidance method based on online trajectory optimization and optimal feedback control was proposed for reentry guidance of hypersonic glide vehicle with multi constraints. The mathematical model of the reentry guidance problem with complex multi constraints was established. The reentry guidance strategy which not only can effectively deal with the interior point constraints and decompose the complex terminal constraints but also take online autonomous obstacle avoidance and adapting target change into account was designed. Combining the online trajectory optimization method based on the Radau pseudospectral method and the sequential quadratic programming algorithm with the idea of optimal feedback control based on sample-hold feedback control, the closed-loop optimal feedback guidance method for reentry phase was presented. Numerical simulation results demonstrate that the proposed guidance method shows good autonomous guidance capability and satisfies the real-time requirement for online calculating optimal guidance commands.
