Fragility-Free Global Prescribed Performance Control for Nonlinear Multiagent Systems

Shoufeng Yang

Abstract: In this paper, the fragility-free global prescribed performance control (GPPC) problem for multiagent systems (MASs) is investigated. Firstly, a GPPC strategy is designed for MASs, and the design parameters are independent of the initial conditions, achieving global consensus tracking results. Furthermore, a novel fragility-free control strategy is designed to adjust the performance boundary based on error changes after system stability in real time, avoiding the fragility problem of conventional prescribed performance control schemes. Finally, the proposed control strategy is applied to a simulation example to verify its feasibility and effectiveness.
