Design of a Finite-Time Full-Order Distributed Function Observers for Interconnected Formation Flight Systems

Abstract

Formation flying increasingly emerged as a vanguard force in executing diverse missions. This paper provides a finite-time distributed state observer for interconnected formation flight systems by information exchange. Based on the linear matrix inequalities (LMIs), the designed parameters of the distributed observers can be obtained. At the same time, the computation is greatly reduced by the proposed algorithm. Furthermore, an improved distributed observer based on the preceding design method is proposed to estimate the states of the system more accurately and quickly. In addition, the proposed distributed estimation algorithm can also be applied to networked interconnected systems. Finally, the effectiveness of the proposed algorithm is further demonstrated by numerical examples and meta aircraft configuration that consists of multiple aircraft joined together.
