Predefined-Time Prescribed Performance Funnel Control for Stochastic Multiagent Systems With Input Continuous...

This article investigates a predefined-time tracking control problem for stochastic nonlinear multiagent systems (MASs). A novel continuous-time hysteretic quantizer is proposed for the first time, achieving seamless transitions between quantization levels. Controller chattering is eliminated while an arbitrary configuration of level-specific dwell durations is permitted. A deferred activation function is introduced to remove the dependence on initial state values in the prescribed performance funnel control design. The proposed method guarantees semi-global practical predefined-time stability for all closed-loop signals, with satisfactory tracking performance of the desired signal. The efficacy and robustness of the proposed approach in meeting prescribed performance specifications are validated through numerical simulations.
