带末端角约束的三维最优滑模制导律设计

某型巡航导弹主要攻击地面固定目标,为获得最佳的攻击角度和打击精度,分别在俯冲和转弯平面内设计了理想状态下导弹的三维最优运动。选取具有干扰的系统状态与理想系统状态之间的误差矢量作为滑模面,在滑模控制作用下,使系统状态趋近理想状态,最终获得具有参数鲁棒性的三维最优滑模制导律。仿真结果表明方法能同时满足打击精度及末端角约束的相关要求,实现对目标的三维立体精确打击,满足实际战场的作战需求。

Three-dimensional Optimal Sliding Mode Guidance Law Design with Terminal Angle Constraint

Cruise missile mostly attacks aptotic objects,in order to obtain optimal attacking angle and attacking precision,optimal 3D trajectory of missile is designed in the pitching plane and swerve plane separately.Then,error vector between the system state with perturbations and the ideal one is chosen as sliding mode surface,the system state with perturbations tend to the ideal state under the sliding mode control.Finally,three-dimensional optimal sliding mode guidance law with parametric robustness is obtained....
