Abstract
This article addresses the leader‐following consensus (LFC) problem for time‐varying coupled high‐order nonlinear multiagent systems (MASs) via a novel state feedback adaptive prescribed performance control. Different from existing control, we first design time‐varying prescribed performance functions for different follower agents as distinct discontinuous nonincreasing piecewise differentiable functions with time‐varying decay rates. Taking aforementioned prescribed performance functions and communication errors as variables while considering effects of adaptive parameters and time‐varying coupling, we construct a novel prescribed performance barrier Lyapunov function (BLF) based on a new natural logarithmic barrier Lyapunov function. Under the developed control, the systems achieve global LFC with prescribed performance through the aforementioned Lyapunov function. Finally, a numerical simulation is provided to validate our theoretical results.
This paper investigates the practical prescribed‐time (PPT) tracking control problem for a class of nonlinear non‐strict‐feedback systems with arbitrarily bounded initial states with arbitrarily bounded initial states and employs a radial basis function neural network to approximate unknown and possibly non‐differentia...

This paper studies distributed leader–follower consensus for heterogeneous nonlinear multi-agent systems with different physical orders and channel-dependent matched and mismatched disturbances. A channel-wise fixed-time extended-state observer estimates the lumped disturbance in each state equation, while a finite-ter...
This work studies distributed Nash equilibrium (NE) seeking for nonlinear multi‐agent systems (MASs) subject to bounded disturbances under uncertain communication topologies. Instead of assuming a fixed graph, the time‐varying and uncertain communication links are described by a Takagi–Sugeno (T–S) fuzzy model. For t...

A unified adaptive neural control framework is developed that synergistically combines predefined‐time stabilization, fixed‐time prescribed performance (FTPP) constraints, command‐filtered backstepping, and a dynamic event‐triggering mechanism (DETM), guaranteeing that both transient and steady‐state behaviors rigorous...

The proposed scheme is proven to ensure that all closed-loop signals are practically predefined-time stable with a preassignable settling-time upper bound and the effectiveness of the approach is validated through simulation results on multiple two-link manipulator systems.
