摘    要:针对反装甲车导弹打击目标时落角约束要求,研究了两类典型的具有落角约束的导引律。通过在滑模变结构导引律的基础上引入模糊逻辑控制以减小控制量的抖振和系统能量耗损;在比例导引律的基础上引入时变导航系数与偏置项来满足落角约束。对两种改进制导律的有效性进行了仿真校验。仿真结果表明,与变系数偏置比例导引律相比,模糊变结构控制在干扰影响下仍能保持较高的制导精度。

关 键 词:落角约束  反装甲车导弹  变结构控制  比例导引  鲁棒性

Abstract:Aiming at war requirements of anti-armor missile with terminal angle constraint, two types of guidance law with terminal angle constraint are researched. Fuzzy logic control is added to sliding mode guidance law to reduce the chattering and the energy loss of the system. Time varying navigation coeffi- cients and bias item are applied in proportion guidance law to achieve expected terminal attack angle. Simulation results verify the effectiveness of the presented guidance law and prove that, compared with bi- ased proportion navigation law with variable coefficient, fuzzy sliding mode guidance law is resistant to in- ference and can get high guidance accuracy.
Keywords:terminal angular constraint  anti-armor missile  sliding mode control  proportional nav-igation guidance  robustness
