滑模变结构导引律在防空反导技术中的应用

Application of Sliding Mode Variable Structure Guidance Law in Air Defense and Anti-missile Technology

针对防空反导末制导段攻击机动目标的问题,以零化弹目视线角速率为依据,设计了一种性能较好的滑模变结构导引律。该导引律在攻击机动目标时具有较高的制导精度,整个攻击过程的弹目视线角速率变化较小,有效解决了抖振问题,同时实现了导弹法向过载的合理分配。仿真结果验证了该导引律的有效性。

Aiming at the problem of maneuvering targets in the tenninal guidance section of the air detense missile, a sliding mode variable structure guidance law with good performance is designed on the basis of zeroing the line of sight rate. This guidance law has higher guidance accuracy tor attacking maneuvering target, and the line of sight angle rate is small in the whole attack process, the buffeting problem is solved effectively, and missile nonnal overload is reasonably distributed as well. The simulation results verift the effectiveness of this guidance law.
