摘要
考虑到导弹-目标追逃模型中存在的非线性和不确定性等特点,首先建立在三维坐标系下的反舰巡航导弹-目标的相对运动方程,采用基于零化导弹目标视线角速率的思想,同时把目标机动看成一类有界干扰,应用动态逆方法设计了一种三维末制导律,这种控制方法可以很好地解决系统中存在的强的非线性和不确性因素。仿真结果表明该制导律能够打击机动目标且脱靶量较小,具有较强的鲁棒性。
Considering the nonlinearity and uncertainty in the pursuit-evasion model between the missile and target, the equations of the missile-target relative motion under the 3 D environment are presented. By using the method of dynamic inversion and regarding the target acceleration as a bounded interference, a 3 D terminal guidance law was designed, which was based on the idea of zeroing the speed of the angle of LOS （Line of Sight）. This control law can properly deal with the nonlinearity and uncertainty factors of the system. Simulation result shows that the missile using this guidance law can attack the maneuvering target successfully and the missing distance is extremely small, and the systems have stronger robustness.
