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.
Air defense missiles are required to be able to cope with the complex confrontation environment such as high speed and high maneuverability.Direct force / aerodynamic composite guidance is the key technology in the design of air defense missile guidance system.It mainly studies the control law, steering law of the direct force / aerodynamic compound control missile and Guidance Law, aiming at nonlinear system, a control method based on adaptive inversion theory is proposed. The fuzzy logic method is adopted in the direct / gas complex switching logic and the variable structure guidance law is adopted in the final guidance section. Taking an air defense missile as an example, The results show that the composite guidance method is easy to implement and has good guidance accuracy for high maneuvering targets. It shows the effectiveness of the proposed method.
