摘　　要：针对多飞行器协同攻击舰船等低速运动目标的问题,首先基于固定时间收敛控制理论设计攻击静止目标的攻击时间控制制导律,在此基础上,将运动目标引起的剩余飞行时间动态变化项视为扰动,利用线性扩张状态观测器对其估计并补偿,实现目标低速运动时的攻击时间控制。进一步考虑战场环境中飞行器网络的有向通信拓扑结构,利用多智能体固定时间一致性方法设计领导-跟随策略下的协同制导律。最后利用仿真试验验证了所设计协同制导律的有效性。Aiming at the problem of multi-aircraft salvo attacking low speed moving targets such as ships,a impact time control guidance law based on fixed-time convergent is designed for a stationary target.On this basis,the dynamic change of the remaining flight time caused by the moving target is regarded as a disturbance,and the linear expansion state observer is used to estimate and compensate it to realize the attack time control when the target is moving at a low speed.Considering the directed communication topology of the aircraft network in the battlefield environment,the fixed-time consensus of multi-agents is utilized to design cooperative guidance in the leader-followers strategy.Simulations are performed to verify the effectiveness of the designed cooperative guidance laws.
