摘要: 防空导弹要求能够应对高速、高机动性等复杂对抗环境,直接力/气动力复合制导是防空导弹制导系统设计的关键技术.主要研究了直接力/气动力复合控制导弹的控制律、操纵律以及制导律,针对非线性系统,提出了一种基于自适应反演理论的控制方法;直/气复合切换逻辑采用模糊方法;末制导段应用变结构制导律.以某防空导弹为例进行仿真,结果表明该复合制导方法易于实现,对于高机动目标具有良好的制导精度,显示了该方法的有效性.

Abstract: Combat environment for air-defense missile is very complex, for example, high-speed and high- maneuverability. Reaction-jet and aerodynamics compound control and guidance technology is the crucial problem of air-defense missile control and guidance system design. The control law and guidance laws for reaction-jet and aerodynamics compound guidance missile were investigated. A control method based on adaptive backstepping theory was put forward for the non-linear system. Fuzzy logic was applied to the design of compound steering law. A variable structure guidance law was proposed for 3-D terminal interception. Taking an anti-air missile as an example, simulation results show that the guidance and control system is easy to realize and has fine guidance precision for a high-speed maneuvering target, and it proves the effectiveness of the method.
