为提高末制导段导弹制导系统对目标机动的鲁棒性，基于变结构控制理论设计了一种模糊变结构末导引律。首先，利用变结构控制理论推导了一种变结构末导引律；其次，为削弱变结构末导引律的抖振，增强导引律鲁棒性能，通过多次仿真计算，找到目标不同机动情况下的理想导引律参数，再基于模糊控制理论，根据加速度的估计值调整变结构导引律参数；最后，将所设计的模糊变结构末导引律与传统变结构导引律、比例导引律进行仿真对比，结果表明，模糊变结构导引律对目标机动具有较强鲁棒性。

In order to improve the robustness of missile guidance system to target maneuvering in the terminal guidance phase,a fuzzy variable structure guidance law was designed based on the variable structure control principle.Firstly,a variable structure guidance law was deduced through the theory of variable structure control.Then,the ideal guidance law parameters were found through simulations to reduce the chattering of guidance and enhance its robustness to target maneuvering .Moreover,the parameters of the guidance law were adjusted according to the target maneuver estimation by means of fuzzy control .At last,the designed terminal guidance law was compared with the traditional variable structure and proportional navigation guidance law . The simulation results show that designed guidance law has stronger robustness to target maneuvering .
