| 摘要: |
| 为充分利用高超声速飞行器在俯冲段的质心运动与绕质心运动之间的耦合作用和飞行过程中的不确定性，基于模糊干扰观测器提出三维一体化制导与控制问题。根据飞行器的动力学方程以及飞行器-目标的视线角相对运动方程，推导出适用于倾斜转弯控制的一体化制导控制模型。针对模型中的不确定性采用模糊干扰观测器进行补偿，并使用块动态面方法设计一种一体化制导控制律。通过选取适当的李雅普诺夫函数证明闭环系统状态的一致毕竟有界性。仿真结果验证了该一体化制导控制方法的有效性和鲁棒性。 |

| Abstract: |
| A three-dimensional IGC (integrated guidance and control) approach based on fuzzy disturbance observer was proposed to take advantage of the coupling between the centroid motion, and the attitude motion, and of the uncertainties of a hypersonic vehicle in dive phase as well. An IGC model that can be applied to bank-to-turn control strategy was proposed according to the dynamic equations of the vehicle and the line-of-sight relative motion between the vehicle and the target. The uncertainties in the model were compensated by utilizing the fuzzy disturbance observer, and then an IGC approach was developed by using the block dynamic surface backstepping control method. The states of the closed loop system were proved to be uniformly ultimately bounded by adopting proper Lyapunov functions. Simulations show that the IGC method is robust to the uncertainties and satisfies the required performance. |
