Leader-Following Exponential Consensus for Higher-Order Fractional-Order MASs With Mismatched Disturbances and Event-Triggered Input
研究了非线性分数阶多智能体系统在未知不匹配扰动和事件触发输入下的领导者跟随指数输出一致性问题，设计了有限时间高阶滑模观测器和分布式积分滑模面，实现了无Zeno行为的一致性控制。
The leader-following exponential output consensus (LFEOC) problem of nonlinear fractional-order MASs (FOMASs) with unknown mismatched disturbances and event-triggered control (ETC) input is investigated. First, a finite-time higher-order sliding observer is constructed for the estimation of the unknown matched and mismatched disturbances of each agent. Second, a distributed integral sliding-mode (ISM) surface is established to realize exponential stabilization of FOMASs, and a distributed event-based active anti-disturbance consensus protocol is designed to compensate the effects of unmatched uncertainties on the output and save energy. Third, it is proved that the output of all agents can be driven to achieve exponential consensus without Zeno behavior, and the corresponding event-triggered conditions are presented. Finally, the efficacy of conclusions is verified by the examples.
