Application of State Observer in the Logistics Alliance Stability

According to the control theory that state feedback could make system stabilized and observer could solve the problem of unobserved state, this paper first proved the feasibility of achieving state feedback with observer, then analyzed design principles of state observer, equivalence of the closed-loop system and separation principle, finally applied the ideas and methods of state feedback and observer into the study of logistics alliance stability, and through a simulation example, the simulation curves of original system, closed-loop state feedback system and six state variables are got, the effectiveness of the proposal is verified. The results show that the method can provide a new insight into the analysis of logistics alliance stability.
