摘　　要：针对时延问题对集群稳定性的影响,对牵制控制策略进行研究,利用反馈线性化将水下无人潜航器(AUV)模型简化为二阶积分器模型,研究了具有时延的水下无人潜航器集群下的编队控制问题,并将一致性控制与牵制控制相结合。分析了输入时延和通信时延对水下无人潜航器集群系统的影响,应用Nyquist判据控制理论进行证明,得到了集群中被牵制水下无人潜航器和未被牵制水下无人潜航器组成的系统能渐进收敛达到一致性的充分必要条件。通过数值仿真验证了定理的正确性。Addressing the impact of latency issues on cluster stability.The traction control strategy is studied.Through the use of feedback linearization,the autonomous underwater vehicle(AUV)model is reduced to a second-order integrator model.The formation control problem of multiple AUV clusters with time delay is examined,and the traction control and consistency control are combined.The influence of input delay and communication delay on the AUV cluster system is analyzed.The Nyquist criterion control theory is used to prove it.We provide the sufficient and necessary conditions for the system’s asymptotic convergence,which is made up of the cluster’s pinned and unpinned AUV.Finally,the correctness of the theorem is further verified by numerical simulation.
