摘要
主要研究了直接力/气动力复合控制导弹的控制律、操纵律以及导引律,针对非线性不确定控制系统,提出了一种基于自适应退步理论的控制方法;利用模糊控制实现了直/气复合控制;针对三维空间末制导段拦截问题,设计了一种变结构末导引律,从而实现了直/气复合导弹制导系统的完整闭环回路仿真。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导引精度,显示了该方法的有效性。
Reaction-jet and aerodynamics compound control,steering law and guidance law are studied.A control system is designed based on adaptive backstepping theory for the non-linear system,a steering law is designed based on fuzzy logic for the compound control system,a variable structure guidance law is proposed for 3-D terminal interception,and the complete closed loop of the guidance system is built up.Simulation results show that the guidance and control system is easy to apply and has fine guidance precision for a high-speed maneuvering target,and it proves the effectiveness of the method.
