This paper addresses the problem of leader-follower consensus for a class of nonlinear multi-agent systems with Lipschitz-type dynamics and a directed communication topology. First, in order to reduce communication frequency among followers, an output-based event-triggered control strategy is proposed for leader-following consensus. Second, neural-network-based observers are designed to reconstruct those immeasurable information of follower agents. Third, instead of continuously monitoring follower agents’ measurements, a distributed self-triggered control strategy is put forward, which is based only on each agent’s local estimation and its previous triggered instants. Furthermore, it is proved theoretically that the consensus tracking errors are ultimately bounded and the Zeno behavior is definitely excluded. Finally, simulation results are given to show the effectiveness and advantage of the proposed results. [ABSTRACT FROM AUTHOR]

The problem of event-triggered real-time scheduling stabilization of Takagi–Sugeno fuzzy system is investigated in this paper. Firstly, a weighted matrix approach is introduced in order to exploit implicit information of a class of nonlinear plants more freely. Secondly, by taking account of the joint-distribution of both past and current normalized fuzzy weighting functions, an event-triggered real-time scheduler is proposed to decide which control mode is to be activated at each sampling instant. Specifically, all the activated control modes can be duly updated with their respective gained matrices for accommodating different time-variant situations provided that the current joint-distribution varies. As a result, the existing stabilization implementation quality can be significantly improved while the computational burden does not increase. Finally, the effectiveness and merits of the proposed method are verified via two simulation examples. [ABSTRACT FROM AUTHOR]

In this paper, we study the finite-time distributed event-triggered consensus control for multi-agent systems. The controllers and the events are designed in a distributed manner, based only on local information. Compared with conventional asymptotic consensus, finite time consensus can reach consensus faster and have better disturbance rejection properties. Thus, we propose a new nonlinear distributed control protocol to achieve finite-time consensus. Moreover, in order to realize the consensus control for multi-agent systems, only the communication between the agent and its local neighbors is needed, therefore, the designed control is essentially distributed. Two sufficient conditions are proposed to reach finite-time consensus for multi-agent systems with fixed and switching network topologies, respectively. Finally, two simulation examples are presented to demonstrate the effectiveness of the theoretical results. [ABSTRACT FROM AUTHOR]
