Yue Wang, Yonghui Yang, Li‐Bing Wu · International Journal of Systems Science · 2025
This article aims to research the problem of predefined time event-triggered control (ETC) for non-affine nonlinear multi-agent systems (MASs) with dead-zone input. Firstly, the fuzzy logic system (FLS) is used to approximate the unknown nonlinear terms once the transformation is completed for non-affine terms. The second is to design a predefined time adaptive control. Through the design of the controller, MASs achieve practical predefined time stable (PPTS), which means the tracking error to converge to the neighborhood close to zero within the predefined time. Importantly, the specified duration can be determined flexibly depending on physical constraints because it is not dependent on the system's initial state. Additionally, to lessen the communication burden and successfully prevent Zeno behaviour, a generalised fixed threshold threshold event-triggered method is also developed. Lastly, the simulation results confirm the proposed algorithm's validity.
