| 中文摘要 |
| 为了突破舰艇配备的近程防御武器系统, 反舰导弹需对撞击时间与撞击角度进行控制, 以实施饱和攻击. 导弹三维撞击时间与撞击角度控制分为两个阶段进行. 第1阶段: 将导弹侧向运动与纵向运动进行近似解耦, 对这两个运动通道分开设计. 在侧向运动中将撞击时间控制转化为对标称弹目距离的跟踪问题, 并对此跟踪问题采用时标分离的方法设计期望的慢子系统和快子系统; 在考虑对方位角粗略控制的同时, 对这两个子系统分别进行动态逆
控制设计, 从而得到了侧向通道控制指令; 在纵向运动中只进行高低角的粗略控制, 不考虑撞击时间控制. 第2阶段: 在考虑两个通道耦合的情况下, 基于李雅普诺夫稳定性理论, 设计了带有撞击角度控制的三维导引律. 仿真结果证明了本文方法的有效性. |
| 英文摘要 |
| The control law for the impact time and the impact angle is applied to carry out a saturation attack for anti-ship missiles against close-in weapon system(CIWS). The 3-D missile control for the impact time and the impact angle consists of two stages. In the first stage, the missile kinetics is decoupled approximately into yaw channel and pitch channel. In the yaw channel, the impact time control problem is transformed into a range-to-go tracking problem, and then, the desired slow subsystem and the fast one are designed by using the time-scale separation method. Considering coarse control to azimuth, we separately design the inverse dynamic controllers for the above two subsystems, and derive the yaw control command. In the pitch channel, only a coarse control of the elevation angle is considered, the impact angle control is ignored. In the second stage, we derive the 3-D guidance law with impact angle constraints for the coupled system using Lyapunov stability theory. Simulation results validate the proposed approach. |
