通信长时间中断的分布式自主协同制导策略

Distributed autonomous cooperative guidance strategy for long time communication interruption

针对通信长时间中断条件下的时空协同制导问题,提出了基于协调到达时间虚拟计算的自主协同制导策略,研究了飞行器单体的攻击时间与角度控制制导方法,构建了以剩余飞行时间为协调变量的分布式双层协同制导结构。在通信中断条件下,提出了无时间控制最优制导、定速控制、到达时间在线装订、协调时间拟合四种协同制导方法,实现了通信断开后等时抵达目标。对上述通信条件下协同制导进行仿真,验证了各类方法在不同飞行条件下的可行性,并针对关键的误差以及能耗指标进行了分析。结果表明,各类方法均能实现协同飞行,但其性能表现与使用场景各不相同,其中使用时间进行数据拟合的方法效果最优。

In order to solve the problem of spatio-temporal cooperative guidance under the condition of long time communication interruption,an autonomous cooperative guidance strategy based on the virtual calculation of coordinated arrival time is presented.An attack time and angle control guidance method of aircraft is studied.A distributed two-layer cooperative guidance structure with the remaining flight time as the coordination variable is constructed.Under the condition of communication interruption,four cooperative guidance methods are proposed to achieve cooperative flight,namely optimal guidance without time control,cruise control,online binding of arrival time and coordination time fitting.The cooperative guidance under the above communication conditions is simulated to verify the feasibility of various methods under different flight conditions,and the key error and energy consumption indicators are analyzed.The results show that various methods can achieve cooperative flight,but their performance and usage scenarios are different.Among them,the method that uses time for data fitting has the best effect.
