具有落角约束的对地攻击自适应变结构导引律

A Terminal Guidance Law of the Self-adaption Variable Structure Considering Angular Constraint for Air-to Ground Attacking

针对空对地攻击武器对地面目标的精确打击问题,提出了一种带落角约束的自适应滑模变结构末制导律。该制导律在自适应滑模导引律的基础上,引入落角约束项,可以满足制导精度和落角的双重要求。仿真结果表明,该制导律对地面活动目标的攻击既具有较高的制导精度,又可以满足落角要求,对空地精确制导武器的作战使用具有指导意义。

Aiming at the problem that air-to-ground weapons attack precisely,a terminal guidance law of the self-adaption variable structure with sliding mode considering angular constraint was deduced.Based on the self-adaption variable structure,the angular constraint was introduced,so that the guidance law could meet the demands of both guidance precision and impact angle.The simulation result shows that the guidance law not only has good guidance precision when attacking moving target on the ground,but also can fit the angular constraint.The result is instructive for combat operation of air-to-ground precision guided weapons.
