This paper concerns the predefined-time bipartite consensus control for uncertain nonlinear multiagent systems under a signed directed topology. All agents have high-order uncertain nonlinear dynamic characteristics satisfying a time-varying Lipschitz growth condition, and their partial state information is not available for measurement. In this case, we put forward a novel output-feedback-based predefined-time leader-following bipartite consensus control strategy. A predefined-time compensator

This article studies the finite-time observer-based leader-following consensus problem for a class of nonlinear multiagent systems with nonuniform time-varying input delays. Existing works usually assume that input delays are the same constants and the input of the leader is available for each follower. In this article, we propose a new distributed consensus algorithm to relax the conservative condition. A novel finite-time distributed observer is designed for each follower, which can accurately

This article addresses the distributed asynchronous consensus problem for nonlinear multiagent systems with switching topologies. Different from the existing results, we consider the detection delay of topology modes and some topologies having no directed spanning tree with leader as the root. In these conditions, the distributed asynchronous switched observer is first developed for each follower to accurately estimate the state information of the leader. Then, an output feedback distributed con

This article addresses the leader-following consensus problem of feedforward stochastic nonlinear multiagent systems with switching topologies. Output information for all agents, except for state information, can be acquired based on sensor measurement. Moreover, the stochastic disturbances from external unpredictable environments are considered on all agent systems with a feedforward structure. In these conditions, we propose a novel consensus scheme with a simple design procedure. First, for e

This article addresses the leader-following consensus problem for multiagent systems with unknown output measurement sensitivity based on a fixed directed topology. Different from the existing works on the consensus problem, the output measurement sensitivity is described as a total unknown parameter. Under this nonideal condition, we put forward a distributed output-feedback consensus control algorithm for the first time. To start with, we design the novel distributed high-gain observer and a h

This paper addresses the output feedback distributed containment control problem for a class of nonlinear stochastic multiagent systems under a fixed directed graph. Existing works usually design the containment control protocol using backstepping design method based on a conservative Lipschitz condition on nonlinear functions, which has a tedious control design procedure. In this paper, a new output feedback distributed containment control algorithm is proposed based on a novel dynamic compensa

This article considers the distributed output-feedback consensus control problem for nonlinear multiagent systems subject to input delays. Different from the existing related works, the input delay of each agent is described as an unknown time-varying function and is different from each other in this article. To deal with this problem, for each follower, we first construct a novel distributed observer based on the relative output information to asymptotically estimate the state information of th

This article is concerned with the distributed leader-following fault-tolerant consensus control problem of uncertain nonlinear delayed multiagent systems with hybrid faults including actuator faults and sensor faults. The faults are described as unknown time-varying functions, which can cause uncertain changes in the fault coefficients of sensors and actuators. In this case, we put forward a novel distributed consensus algorithm. First, we transform the consensus problem into the stability one

This article focuses on distributed consensus control for nonlinear multiagent systems under directed graphs of dynamic frequency switches. The agents exchange information with each other through directed graphs that are switched based on a new general switching law. Not all graphs contain a spanning tree with the leader as the root. Under this condition, a novel distributed switched observer is constructed for each follower, and it can accurately estimate the state information of the leader by

This paper explores the distributed leader-following bipartite consensus control issue for nonlinear multiagent systems under switching signed topologies and communication delays. It is permitted that the signed topologies are switched with an average dwell-time condition, and the delays are modeled as the time-varying functions. In the permission, we develop a new dynamic output feedback control-based distributed bipartite consensus method. First, we put forward the delays-dependent distributed

This article investigates the problem of the fixed directed topology-based leader–following consensus control for nonlinear multiagent systems with output delays. Diverging from existing results, this study focuses on large time-varying output delay. Taking this condition into account, a novel delay classification-based distributed output feedback consensus algorithm is developed. First, we divide the output delay into two types through a designed constant and introduce a switching signal to dis
