| 摘要: |
| 面向多约束下高超声速飞行器末制导过程中的通道耦合、参数扰动、模型失配等突出问题，设计一种适于高超声速飞行器的三维非线性自适应末制导律。为了模型描述的完整性和简洁性，引入视线旋量和旋量速度的概念，并基于此建立三维制导参考模型和实际系统的表达式；为了保证制导律的鲁棒性和自适应性，基于自适应控制理论，设计一种三维非线性自适应制导律；通过数学推导证明了该制导律的稳定性。该制导律能够从理论上克服高超声速飞行器末制导面临的通道耦合、参数扰动、模型失配等突出问题，满足多约束制导要求。仿真结果验证了所设计制导律的有效性。 |

| Abstract: |
| Aiming at the multi-constraint terminal guidance of hypersonic vehicle, a novel 3D (three-dimensional) nonlinear adaptive terminal guidance law was proposed to resolve the problems of channel coupling, parameter perturbation and model mismatching. For the integrality and concision in model description, a 3D guidance reference model and its corresponding practical guidance system were both constructed on the basis of the concepts about line-of-sight twist and its rate. In order to guarantee the robustness and adaption, a 3D nonlinear adaptive guidance law was deduced on the basis of the adaptive control theory. The stability of this guidance law was proved through mathematical deduction. With this novel guidance law, the channel coupling, parameter perturbation and model mismatching problems were avoided and the multi constraint of terminal guidance was satisfied as well. The validity of this guidance law was also validated through simulation experiments. |
