将弹头-目标相对运动关系分解为纵向平面和侧向平面内的相对运动关系,对非自旋弹头的制导问题进行了研究.为了保证非自旋弹头打击地面目标时的脱靶量和末端落角同时满足要求,提出了一种变结构制导律,该制导律在滑模面设计中同时包含了脱靶量和末端落角两种因素.采用指数趋近律方法来分别设计了纵向平面和侧向平面内的变结构制导律.仿真结果表明,所提出的变结构制导律不仅保证了脱靶量指标,而且使非自旋弹头以期望的末端落角命中目标,有效地提高了对目标的毁伤强度.
The relationship between warhead-target relative motion is decomposed into the relative motion between longitudinal plane and lateral plane, and the guidance problem of non-spin warhead is studied.In order to ensure the miss distance and the terminal falling angle At the same time to meet the requirements, a variable structure guidance law is proposed, which contains both the miss distance and the terminal falling angle in the design of sliding surface.The exponential approach law is used to design the longitudinal plane and lateral direction Plane variable structure guidance law.The simulation results show that the proposed variable structure guidance law not only guarantees the target miss distance but also makes the non-spin warhead hit the target with the desired tip angle and effectively improves the target damage intensity .
