【摘要】 针对导弹的平面拦截模型,提出了一种非线性自适应制导控制律。当目标的机动角速度为未知(分段)常值时,该控制律可以保证拦截目标。和已有的算法相比,所提出的算法充分利用了已知的量测信息,不需要利用变结构控制项来抵消目标运动的不确定性,具有控制光滑、容易实现的优点。仿真结果证实了算法的有效性。更多还原

【Abstract】 A nonlinear adaptive guidance law is derived for the model of planar missile interception.The proposed guidance law guarantees that the missile can intercept a maneuverable target with unknown constant(piece-wise constant) angular velocity.Compared with the previous results,the proposed one efficiently use the measurable information,and does not need to use variable structure control terms to circumvent the motion uncertainty of the target,and thus is smooth and can be easily implemented.Simulation results verify the effectiveness of the proposed guidance law.更多还原
