摘　　要：基于变结构控制理论,提出了一种设计简单、具有很好鲁棒性及准确性的平滑导引律,解决了某型导弹因采用变结构导引律攻击机动目标时,视线倾角增量变化律的来回切换产生抖动的缺陷。When the missile using the variable structure guidance （VSG） law attacks the target with maneuver, the chattering of line-of-sight angular rate always happens. The smoothness guidance law based on variable structure control theory is presented to solving the problem. Moreover, this guidance law has good robustness and precision. This guidance law avoids the chattering of line-of-sight angular rate of attack missile by introducing the hyperbolic tangent function. The chattering of line-of-sight angular rate is eliminated
