摘　　要：基于三维空间坐标系下的飞行器-目标相对运动方程,应用动态面控制方法设计了一种新型三维空间导引律,并证明了其稳定性。在导引律的设计过程中,通过引入一阶低通滤波器,使得导引律的最终表达形式中不含有中间变量的高阶导数,更易于实际应用。仿真结果表明,在目标非机动和复杂正弦机动两种情况下,采用该导引律的飞行器都能够获得较小的脱靶量,并且在目标机动时,该导引律具有更高的制导精度。A new three-dimensional （3D） guidance law is designed by using the dynamic surface control method based on the vehicle-target dynamics in 3D coordinates, and the stability of the guidance law is proved. Some first-order, low-pass fihers are introduced into the designing process to avoid the occurrence of high-order derivatives of intermediate variables in the expression of the guidance law, which makes it easy to implement in practical applications. Simulation results show that ： 1 ） The vehicle using this guidance law can obtain smaller miss distance in both the cases that the target is non-maneuvering and is making complicated sinusoidal maneuvering; and 2） When attacking maneuvering target, this guidance law can achieve higher guidance accuracy.
