摘　　要：在三维空间中,根据导弹与目标的运动学关系,建立了导弹拦截的三维模型,分别针对目标非机动和机动的情形,充分利用已经测得的信息,采用自适应方法建立了一种新的非线性导引律,并且运用Barbalat引理以及Lyapunov方法严格证明了导引律的正确性,它能够保证拦截全局一致有界。和已有的控制律相比,该导引律具有设计简单,控制光滑,容易实现的特点,避免了使用变结构控制时所导致的自激震荡。仿真结果验证了控制律的有效性。Based on the kinematic relationship between the missile and target,a 3-dimensional model for missile interception was formulated in three-dimension space.Using measuring information and applying adaptive method,a new nonlinear guidance law was derived aiming at interception of non-maneuvering and maneuvering targets.The correctness of the guidance law was strictly proved by using Barbalat lemma and Lyapunov theory.The intercept guidance law can achieve global ultimate boundedness.Compared with the previous results,the proposed one is smooth and can be easily implemented,and avoids chattering which resulted from variable structure control law.Simulation results verify the effectiveness of the proposed guidance law.
