为了完成反舰导弹按预定方向打击目标的战术要求,基于三维弹目相对运动模型,将落角要求约束在滑模面上,然后通过模糊系统对非线性模型进行逼近,设计了一种带有落角约束的三维自适应模糊滑模导引,并根据Lyapunov稳定性定理,从理论上证明了制导系统的稳定性。仿真结果表明了本文方法的正确性和有效性。

In order to achieve the tactical mission of accurately attacking the target,based on relative motion model of missile and target,a 3-D adaptive fuzzy sliding mode guidance law with impact angle constraint is proposed by constraining the impact angle on the sliding mode,and the anti-ship missile model is approximated by fuzzy system in case that the precise nonlinear model is not obtained.The stability of the guidance system is theoretically proved by Lyapunov stability theory.The numerical simulation result shows the validity and effectiveness of the proposed method.
