| 摘要: |
| 采用高阶滑模控制方法（HOSM，high order sliding mode），对反临近空间高超声速飞行器的拦截弹进行制导控制一体化设计。首先，给出了拦截弹的制导控制一体化模型，并利用高阶滑模控制系统的特点，人为地将系统的相对阶提高一阶，并对升阶后的增广系统进行准连续高阶滑模控制器设计，之后再由虚拟控制积分得到实际控制指令。这种基于高阶滑模虚拟控制的方法可以有效减小抖振，并且不引入符号函数近似函数，从理论上完整地保留了滑模控制器的鲁棒性。在进行高阶滑模控制器设计时，通过引入任意阶精确鲁棒微分器（AORED，arbitrary order robust exact differentiator）对滑模面的高阶量进行估计，实际使用效果良好。最后，在3种典型的目标机动情境下，将所设计的一体化方法与传统的"制导律+过载驾驶仪"方法进行仿真比较，仿真结果表明，一体化方法不仅具有更小的脱靶量，而且过载指令收敛迅速，能够以更小的过载消耗实现对目标的拦截。 |

| Abstract: |
| This paper focuses on the integrated guidance and control (IGC) method applied in the interception of maneuvering near space hypersonic vehicles using the homogeneous high order sliding mode (HOSM) approach. The IGC model is derived by combining the target-missile relative motion and dynamic equations. Then, a fourth order sliding mode controller is implemented in the augmented IGC model, To estimate the high order differentiate of the sliding manifold which is required in the HOSM method, an arbitrary order robust exact differentiator is present. At last, the idea of virtual control is introduced to alleviate the chattering of the control input without using any saturation functions which may lead to a loss of the robustness. And the stability of the fourth order homogeneous HOSM controller is also proved theoretically. Finally, simulation results are provided and analyzed to demonstrate the effectiveness of the proposed method in three typical engagement scenarios. |
