ABSTRACT The design of distributed observers is a hot topic in the research of multi-agent system. It can estimate the whole states of the plant with only portion of output information and the information communicated in the network. This paper introduces the high-gain matrix into the classical distributed observers to improve its convergence speed. In this scene, the performance of distributed observers-based control law can be improved. Since high-gain matrix change the structure of classical distributed observers, a group of sufficient conditions for the stability of the distributed high-gain observers are proved. Moreover, we prove the distributed high-gain observers-based control law satisfies certainty equivalency principle and the designed observer has performance recovery capability. A numerical simulation demonstrates the correction and superior property of our method.

基于分布式高增益观测器的动态性能更好的分布式观测器控制律

摘要 分布式观察器的设计是多智能体系统研究的一个热点。它可以仅用部分输出信息和网络中传递的信息来估计工厂的整体状态。本文将高增益矩阵引入经典分布式观测器以提高其收敛速度。在这种情况下，可以提高基于分布式观测器的控制律的性能。由于高增益矩阵改变了经典分布式观测器的结构，证明了分布式高增益观测器稳定性的一组充分条件。此外，我们证明了基于分布式高增益观测器的控制律满足确定性等效原理，并且设计的观测器具有性能恢复能力。
