This book focuses on anti-disturbance intrusion- and fault-tolerant consensus control for MASs. The main feature of this book is the successful introduction of event-triggered distributed adaptive feedback control methodology, observer technology, and sliding mode technology to solve the problem of anti-disturbance, intrusion-tolerant, and fault-tolerant control of MAS. Meanwhile, pinning control strategies are proposed to realize the cluster consensus control of MAS. In addition, based on the Nussbaum function, the fault-tolerant control problems of different types of MASs subjected to time-varying unknown nonidentical direction (TVUND) faults are investigated. This book provides a coherent approach and contains valuable reference materials for researchers who wish to explore the area of MAS. Researchers, graduate students, and engineers in the fields of electrical engineering, control engineering, applied mathematics, computer science, and others will benefit from this book.
