Distributed Fault Estimation for Uncertain Multiagent Systems With Directed Graphs
Wang Shenquan, Shuaiqi Chen, Wenchengyu Ji, Yuenan Wang · 2019
A distributed fault estimation observer (DFEO) for uncertain multiagent systems (MASs) is proposed in this paper. At first, based on the communication topology of MASs a relative output estimation error is defined. Secondly, in order to enhance the accuracy of fault estimation a DFEO with adjustable parameter (AP) is constructed. The gain of DFEO, based on H∞pole placement (PP), is calculated by multi-constraint design method. Finally, a more reliable and efficient DFEO is proposed by introducing AP,the feasibility was shown by simulation results. Keywords: Adjustable parameter, uncertain multiagent systems, distributed fault estimation.
