为提高弹头打击固定目标的作战效能,机动飞行器一般会有终端约束,如弹道倾角、法向过载等。运用反演滑模设计方法,不需要线性化,可逐阶满足各个终端约束,给出了一种能够满足终端弹道倾角和法向过载约束的末端导引方法。仿真结果表明,该方法具有较高的制导精度,且在多种扰动情况下具有较好的鲁棒性。 In order to improve the combat effectiveness of the fixed targets of warhead combat, the maneuvering vehicles generally have terminal constraints, such as ballistic inclination, normal overload and the like. Using the backstepping sliding mode design method, it does not need to be linearized and can satisfy each terminal constraints step by step. A terminal guidance method that can satisfy the terminal ballistic obliquity and normal overload constraints is given. Simulation results show that the proposed method has high guidance accuracy and robustness under many disturbances.
