Online cooperative learning for nonlinear multi-agent systems with quantised states and inputs under switching topologies

This paper addresses the problem of fuzzy adaptive state and input quantisation control for nonlinear multi-agent systems (MASs) under switching topologies and directed graphs. The fuzzy logic system (FLS) is employed to approximate unknown nonlinear functions, while a second-ord...

Investigating high-temperature wear behavior and mechanism of (TiC+TiB+La2O3)/TC4 composites via finite element simulation and experiments

A pin-on-disk friction model was proposed based on the Archard theory, incorporating the arbitrary Lagrangian-Eulerian (ALE) remeshing technique and the Umeshmotion subroutine in Abaqus software. The model simulated the friction process between (TiC+TiB+La 2 O 3 )/TC4 composites...
