摘　　要：面向三维场景下的多导弹协同攻击机动目标问题,基于固定时间稳定理论和自适应滑模控制理论,设计考虑时间及空间约束的分布式协同制导律。在弹目视线方向上,基于固定时间一致性理论提出一种改进型自适应鲁棒协同制导律,驱动弹群以期望的攻击时刻协同拦截机动目标,并避免滑模固有的抖振问题;考虑视线法向的空间约束,基于固定时间非奇异终端滑模控制理论设计一种鲁棒自适应滑模制导律,在实现终端碰撞角约束的同时避免弹群间碰撞。通过Lyapunov稳定性理论证明闭环系统的固定时间稳定性。仿真结果表明:所设计三维协同制导律可以有效控制多发导弹在期望攻击时刻同时打击机动目标,并以期望的终端角度攻击目标。Aiming at the problem of three-dimensional multiple missiles intercepting a maneuvering target simultaneously,a three-dimensional distributed cooperative guidance law considering time and space constraints.The proposed guidance law is based on fixed-time stable theory and adaptive sliding mode theory.Along the light-of-sight(LOS)direction,an improved robust adaptive cooperative guidance law is presented based on fixed-time consensus,which can drive a group of missiles to attack maneuvering target at a desired impact time without inherent chattering of sliding mode control.Along the direction vertical to the line-of-sight,a robust adaptive guidance law is proposed based on nonsingular fixed-time terminal sliding mode technique,which can drive missiles attack target with desired impact angle and avoid collision between missiles.Through the Lyapunov stability theory,the fixed-time stability of closed-loop system is demonstrated.The simulation results show that the proposed approach can be implemented to intercept maneuvering targets with desired impact time and impact angle.
