Abstract

This paper concerns with the problem of adaptive observer-based fault estimation of linear multi-agent systems with actuator faults. An undirected multigraph is used to represent the communication topology of a group of leader-follower vertical takeoff and landing (VTOL) aircrafts, and one method of fast adaptive fault estimation (FAFE) using relative output estimation error is proposed to achieve fault estimation for such multi-agent systems. Based on linear matrix inequality (LMI) technique, an effective algorithm is designed to obtain the related parameters. Simulation results show the effectiveness of the proposed method for multi-agent systems' fault estimation.
