摘要：This paper proposes a hierarchical-structure-based fault estimation and fault-tolerant control design with bidirectional interactions for nonlinear multiagent systems with actuator faults. The hierarchical structure consists of distributed multiagent system hierarchy, undirected topology hierarchy, decentralized fault estimation hierarchy, and distributed fault-tolerant control hierarchy. The states and faults of the system are estimated simultaneously by merging the unknown input observer in a decentralized fashion. The distributed-constant-gain-based and node-based fault-tolerant control schemes are developed to guarantee the asymptotic stability and H-infinity performance of multiagent systems, respectively, based on the estimated information in the fault estimation hierarchy and the relative output information from neighbors. Two simulation cases validate the efficiency of the proposed hierarchical structure control algorithm. © 2014 IEEE.
