This paper investigates the problem of steering a group of autonomous underwater vehicles along specified paths while keeping a desired spatial formation. Based on passivity and consensus tracking theories, a distributed control strategy was derived, by which the consensus formation tracking problems for a group of autonomous underwater vehicles can be accomplished, when the common reference velocity signal is available to only a subset of the cooperating vehicles. The proposed control strategy can be divided into two parts. Firstly, a passivity channel from coordinated error to tracking error is established based on the passivity theory. Secondly, a coordinated consensus tracking strategy is derived to ensure each AUV for reaching a consistent state about the inconsistent reference information. The stability of the overall closed-loop system is analyzed mathematically by adopting Nested Matrosov theorem. Simulation results are presented and discussed for validating the proposed controller.%研究了自主水下航行器的编队路径跟踪问题.基于无源性理论与一致性跟踪理论,在仅有部分AUV获取编队速度信息情形下,设计一种分布式控制律,实现了集群AUV的一致性编队跟踪.控制律分为2个部分:一部分基于无源性同步原理,建立了协同误差到跟踪误差的无源性通道；另一部分为一致性协同跟踪控制器,保证每个AUV相对于虚拟领航者的不一致参考信息通过协商达到最终一致状态.文章应用Nested Matrosov定理证明了整个闭环系统的稳定性,仿真结果验证了上述方法的有效性和可行性.
