Abstract

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 $H_{\infty}$ 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.
