带落角约束的末端机动Terminal滑模导引律设计

为了提高反舰导弹的突防概率，有效规避敌方舰空导弹的拦截，并且实现反舰导弹按预定方向精确打击目标的战术要求，首先，基于弹目之间的三维相对运动模型，应用Terminal滑模控制理论，设计了一种带有落角约束的变结构导引律；然后，通过叠加虚拟干扰的方法，在原来导引律基础上叠加了一虚拟干扰，此虚拟干扰不影响导引律的渐进稳定性，不...

Design of a Maneuver Terminal Sliding Mode Guidance Lawwith Impact Angle Constraints

In order to improve the penetration effect of the- anti-ship missile, avoid to be intercepted by the ship-to-air missile, and achieve the tactical mission of attacking the target on the appointed direction, based on the 3-D relative motion model of missile and target, a Terminal sliding mode guidance law with impact angle constraints, was presented in the point of view of engineering application. Then a virtual interference was added on the proposed guidance law, and the it had no effect on the stability of the guidance system and the attack precision. The suppositional disturbance can offer the enough acceleration of the anti-ship missile, but not exceed the available acceleration. And the virtual interference could produce certain terminal maneuver to avoid the intercepting of the enemy ship-to-air missile. The numerical simulation result showed the validity and effectiveness of the proposed method.
