Prescribed Finite-Time Output Feedback Consensus Tracking for Nonlinear Multi-Agent Systems With Time-Varying Delays

초록

This article concentrates on the prescribed performance control problem of nonlinear time-varying delay (TD) multiagent systems (MASs). This problem is more challenging to address when considering unstructured uncertainties and immeasurable states. By applying the approximation ability of a fuzzy logic system (FLS), a fuzzy state observer is reconstructed. Furthermore, a Lyapunov-Krasovskii functional is employed to cope with TD, after which an FLS-based adaptive prescribed finite-time control scheme, which enables the convergence time and region to be predetermined, is presented. Meanwhile, the boundedness of the signals is guaranteed. Theoretical studies and practical simulations were performed to certify the validity of the presented algorithm.
