摘  要:针对带有终端攻击角要求的拦截弹末制导问题,提出了双闭环制导律。首先,建立弹目相对运动模型,设计内环控制视线角速度,消除目标速度扰动;外环控制视线角,实现视线角跟踪。然后,控制器参数补偿模型非线性参数,简化为线性系统实现视线角跟踪。最后,对该制导律与比例导引律、最优制导律开展仿真,对比分析针对不同速度目标的拦截效果。仿真结果表明:该制导律可实现视线角约束,且其末段弹道较比例导引律的末段弹道更平滑;对于高速的目标,该制导律可以保持良好的拦截效果和角度约束效果。Aiming at the terminal guidance problem of interceptor with terminal attack angle,a double closed-loop guidance law is proposed.The relative motion model of missile and target is established,and the inner loop is designed to control the line of sight angular velocity and eliminate the target velocity disturbance;The outer loop controls the line of sight angle to realize line of sight angle tracking.The controller parameters compensate the nonlinear parameters of the model and simplify it to a linear system to realize line of sight tracking.Finally,this guidance law is simulated and compared with proportional guidance law and optimal guidance law to analyze the interception effect for different speed targets.The simulation results show that the guidance law can realize the line of sight angle constraint,the terminal trajectory is smoother than the proportion guidance law.For high-speed targets,the guidance law can still preserve good interception effect and angle constraint effect.
