摘要 基于变结构控制理论,针对小型水面机动目标,设计了一种新的导弹航向平面导引律,并对导引律中所需要的目标运动信息给出了估算方法。由于导弹的动态特性对脱靶量有较大影响,为此,本文还研究了导弹动态特性补偿的方法。仿真结果表明,在导弹的动态响应特性较好的情况下,该导引律能提供很高的命中精度;在导弹的动态响应特性很差的情况下,对动态特性补偿后,仍可得到很高的命中精度。 A new yaw plane guidance law for missiles against small maneuvering targets on the sea is designed based on variable structure control theory, besides the method of estimating the information on the motion of the target is given ,which is needed in the guidance law. Because the dynamics of a missile has great influence on the miss distance of a missile, the compensation method to the dynamics of the missile is also studied in this paper. Simulation results have shown that when the dynamics of the missile is good, high accuracy of hitting a target can be got, when the dynamics of the missile becomes bad, high accuracy of hitting a target can also be got if the compensation to the dynamics of the missile is considered.
