摘要:

针对可重复使用运载器(reusable launch vehicle, RLV)再入段常规约束、航路点约束、倾侧角速率约束和参数不确定问题, 提出一种多约束鲁棒预测校正制导方法。首先, 利用改进准平衡滑翔条件将常规约束转化为倾侧角幅值约束。其次, 提出基于二分法快速迭代确定倾侧角翻转位置的航路点制导律, 并将翻转速率约束转化为关于能量的约束, 引入预测校正的计算中。然后, 对于参数不确定鲁棒制导问题, 提出基于标称升阻比和能量剖面对迎角及横程误差走廊在线调整的策略。仿真实验表明, 在参数不确定情况下, RLV能够满足多约束条件和终端制导精度要求, 验证了方法的有效性和鲁棒性。

Abstract:

Aiming at general constraints, waypoint constraint, reverse rate constraint of bank angle and parameter uncertainties for reusable launch vehicles (RLVs) during re-entry, a kind of robust predictor-corrector guidance method meeting multiple constraints is proposed. Firstly, the modified quasi-equilibrium glide condition is exploited to transform general constraints into the amplitude constraint of bank angle. Secondly, a dichotomy-based waypoint guidance law is presented to speedily determine the reverse position of bank angle, and the reverse rate constraint is converted to that of energy which can be calculated during the prediction correction process. Next, an online adjustment strategy of angle of attack and cross-range error corridor based on the nominal lift-drag-ratio and residual energy is proposed to deal with the parameter uncertainty robust guidance issue. Simulation tests show that the RLV can satisfy multiple constraints and terminal guidance requirement in the presence of parameter uncertainties, which verifies the effectiveness and robustness of the presented method.

Key words: reusable launch vehicle (RLV), re-entry guidance, multiple constraints, predictor-corrector guidance, robust guidance
