摘要
针对多飞行器协同拦截过程中的角度协同问题,设计了一种基于量化编码器的分布式一体化协同制导控制律.首先建立多飞行器协同制导与控制数学模型,并基于扩张状态观测器理论,对单个飞行器各状态进行观测.在此基础上考虑各飞行器间单次传输数据的字长、两次传输数据间隔的通信速率约束,采用量化器-编码器-解码器实现限制通信速率情况下的协同一体化制导控制设计.之后,通过严格的理论分析证明了满足强连通图有向通信网络下,多飞行器系统能够达成一致性且收敛到期望的相对视线角,并给出了满足收敛条件的参数选择范围.最后,通过数学仿真校验,验证了所提出的方法在较低的通信速率下能够完成协同.
Abstract
Based on quantizer and encoder,a distributed integrated guidance and control law is proposed to achieve angle cooperation.Firstly,multi-aircraft guidance and control model is established and states of single aircraft are observed based on the extended state observer.On this basis,considering the communication constraints of digital channels,the quantizer-encoder-decoder is used to realize the cooperative integrated guidance and control law design with limited communication data rate.Through strict theoretical analysis,it is proved that the multi-aircraft system achieves consensus and converges to expected relative line of sight angle under a strongly connected and directed graph communication topology.The range of parameters that meet the convergence conditions is also given.Finally,through mathematical simulation,it is verified that the proposed method can complete cooperation with a low communication rate.
