“…36 Fixed-time consensus for MASs subject to unknown bounded disturbances with event-triggered control protocols is investigated. 37 Leaderless fixed-time MASs consensus with nonlinear dynamics is achieved under ETC. 38 However, general ETC is a zero-order hold (ZOH) in the triggered intervals, which cannot utilize the performance of the controller better.…”

To address model-based event-triggered fixed-time consensus of nonlinear multi-agent systems with both fixed topology and switching topologies, a novel model-based event-triggered protocol is presented. In the proposed protocol, agents in multi-agent systems update controllers by utilizing estimated state values in the triggered intervals. And for reducing the burdens of bandwidth further, the model-based event-triggered protocol is extended to self-triggered protocol which does not need continuous communication in triggered intervals. It is proven that Zeno behavior is excluded. Our main contributions are giving a novel distributed model-based event-triggered protocol for fixed-time consensus and extending it into a self-triggered protocol. Finally, a couple of simulation examples are provided to verify the effectiveness of the proposed protocols.

“…It is noted that the closed-loop systems are robust to external disturbances. Then, to obtain better performance in both energy efficiency and convergent rate, event-triggered finite-time protocols were established in [25][26][27][28][29]. In [25], finitetime sliding mode controller under event-triggered strategy was designed for first-order multirobot systems.…”

“…Continuous communication free event-triggered protocol was proposed in [26] to achieve finite-time consensus for MAS with unknown disturbances. In [27] and [28], leaderless and leader-follower disturbed MAS have been studied to achieve finite-time consensus with event-triggered strategies respectively. In [29], disturbed MAS were considered and the leader-follower consensus problem was discussed.…”

Input saturation, which brings input non-linearity to systems and limits the closed-loop systems' performances severely, is an ubiquitous problem in practice. Here, triggered finitetime consensus problem of disturbed leader-follower multi-agent systems is addressed under input saturation constraint. To overcome the coupling of the non-linearity and finitetime convergence together with input saturation, non-linear triggered control protocol has been proposed, which is confirmed through a two-step stabilization procedure. First, the saturated closed-loop system is designed to be asymptotically stable, under which the systems converge into a desaturated region in finite time. Then in the second step, with the proposed control protocol, the desaturated closed-loop multi-agent systems can achieve practical finite-time consensus. In addition, to get rid of continuous communication in the monitoring of event-triggered condition, a self-triggered approach is further proposed. With rigorous analyses, practical finite-time consensus can be achieved for the overall closed-loop systems and Zeno behavior is also excluded. Simulations are carried out in detail to illustrate the theoretical results in this study.
