Abstract
In this article, an adaptive fuzzy event‐triggered fixed‐time prescribed performance (FTPP) containment control scheme is investigated for switched nonlinear multi‐agent systems (MASs). The containment errors can always be suppressed to the prescribed boundary and converge to the steady‐state performance function within the predesigned time via introducing the FTPP function. Fuzzy logic systems (FLSs) are used to identify the uncertain nonlinear items, and a state observer is designed to estimate the unmeasurable states. By integrating backstepping and command filtering, the issue of “explosion of complexity” is eliminated. To reduce the communication redundancy while ensuring the steady‐state performance, an event‐triggered controller (ETC) is designed based on a common Lyapunov function. The proposed containment control scheme can guarantee that all signals in the closed‐loop system are bounded, the output of each agent converges to the convex hull formed by multiple leaders, the containment error can always fall into the prescribed boundary, and converges to the steady‐state performance function boundary at the predetermined time. Finally, the effectiveness of the proposed control method is verified through a simulation example.
