Abstract: With the less stability of logistics alliance system at present and the problem that the states are difficult to be observed during the actual logistics system，this paper applies the idea and method of state feedback and observer into the logistics alliance stability study（state feedback can make system stabilized and observer can solve the problem of states not to be observed）.This provides a new insight into the stability analysis of logistics alliance.Finally，a simulation example validates the effectiveness of the presented algorithms.

摘要： 针对目前物流联盟系统稳定性较差和实际物流系统中状态不可观测的困难，根据控制论中状态反馈可以镇定系统、观测器能够解决状态不可观测的问题，提出把观测器状态反馈的思想和方法应用到物流联盟稳定性研究中，这为物流联盟稳定性的分析提供了一个新视角。最后通过仿真算例验证了所提方案的有效性。
