This article is concerned with the problem of distributed adaptive fuzzy fault-tolerant containment control (FTCC) for a class heterogeneous nonlinear multiagent systems actuator faults and external disturbances. Two FTCC strategies are proposed two different cases, i.e., leader's input can be obtained by its neighboring follower agents leader not available any followers, respectively. In first case, observer-based protocol presented to achieve objective. second method which independent...

In this article, the problem of distributed hierarchical fault-tolerant containment control for heterogeneous linear multiagent systems (MASs) is investigated. most existing methods MASs with system failures, each agent broadcasts its state, or output, estimation state to neighbors. Once an subjected faults affect dynamics other agents over network, that is, influence on will propagate network. order overcome drawback, a protocol developed, which includes two layers: 1) upper layer and 2)...

This paper investigates the distributed fault-tolerant containment control (FTCC) problem of nonlinear multi-agent systems (MASs) under a directed network topology. The proposed framework which is independent on global information about communication topology consists two layers. Different from most existing (FTC) protocols where fault in one agent may propagate over network, developed method can eliminate phenomenon propagation. Based hierarchical strategy, FTCC with graph be simplified to...

This paper investigates modular design problems of reliable distributed bipartite consensus for multi-agent systems (MASs) by using virtual tracking techniques. Virtual reference (VRSs) are introduced at first. The lower-level controller designed is to remove the influence actuator faults and input disturbances, such that each one in MASs tracks corresponding VRS. And then, observer-based upper-level with online adaptive adjustment gain further put forward achieve VRS's consensus. Different...

In this article, the cooperative fuzzy hierarchical fault-tolerant containment control (FTCC) method is proposed for nonlinear multiagent systems (MASs) over switching directed topologies. Based on mechanism, problem of FTCC MASs under topologies decoupled into virtual reference system (upper layer) and tracking actual (lower layer). Due to existence topologies, state may jump, which further affects transient performance lower system; moreover, actuator faults also cause a sudden change in...

Compared existing result, novel method provides two design freedoms developed reduce error. According...

In this paper, the distributed fault-tolerant tracking control (FTTC) problems for uncertain homogeneous and heterogeneous multi-agent systems (MASs) under asynchronous sampled communications are investigated. case of communications, each agent is at its own sampling instants exchanges information to neighbor agents. presence actuator failures, different system dynamics, it difficult accomplish task control. To overcome difficulty, two novel observer-based FTTC protocols MASs proposed....

Society is more and interested in developing mathematical models to assess forecast the environmental biological health conditions of our planet. However, most existing cannot determine long-range impacts potential policies without considering complex global factors their cross effects systems. In this paper, Markov property Neural Network Ensemble (NNE) are utilized construct an estimated matrix that combines interaction different local factors. With such estimation matrix, we could obtain...
