为了提高空地导弹的打击效能,追求最佳的毁伤效果,文中在解耦后的空地导弹目标相对运动模型的基础上,应用基于零化视线角速率的准平行接近原理及滑模变结构控制理论设计了带落角约束的空地导弹滑模末制导律。应用模糊控制理论与RBF神经网络理论,分别对滑模趋近系数与切换项增益系数进行自适应调节。最后,对文中所设计的末制导律进行仿真验证,仿真结果表明该末制导律能够以期望的落角命中目标,具有一定的理论参考价值。

In order to improve the guidance property of the Air-to-ground missile, and achieve the best efficiency of damage. An intelligent sliding mode terminal guidance law for Air-to-ground missile with impact angle was designed based on the decoupled Air-to-ground missile and target relative motion model, the theory of zeroing the rate of line-of-sight angular rate and the sliding mode variable structure control theory. The fuzzy theory was used to adaptive adjust the reaching coefficient, and the RBF neural network was used to adaptive adjust the switching term gain coefficient. Finally, the designed terminal guidance law was verified by simulation, and the simulation results show that the terminal guidance law can hit the target with the expected impact angle, and has a certain theoretical reference value.
