This paper addresses the synchronization problem of multi-agent systems with nonlinear controller outputs via event-triggered control, in which the combined edge state information is utilized, and all controller outputs are nonlinear to describe their inherent nonlinear characteristics and the effects of data transmission in digital communication networks. First, an edge-event-triggered policy is proposed to implement intermittent controller updates without Zeno behavior. Then, an edge-self-triggered solution is further investigated to achieve discontinuous monitoring of sensors. Compared with the previous event-triggered mechanisms, our policy design considers the controller output nonlinearities. Furthermore, the system’s inherent nonlinear characteristics and networked data transmission effects are combined in a unified framework. Numerical simulations demonstrate the effectiveness of our theoretical results.

This paper investigates the co-design problem of both robust integrity and the usage of communication resources for a class of actuator-saturated networked control system(NCS) based on a novel discrete event-triggered communication scheme(DETCS). First, a new model of NCS is established that parameter uncertainty, network-induced delay, actuator saturation and faults, and the state error arising from the DETCS are taken into consideration in a unified framework. Second, based on the model, the set of invariance condition of the closed-loop fault NCS with actuator saturation is proposed, which is the delay-dependent and event-dependent sufficient condition for ensuring the system stability. Then, a co-design approach which includes both robust fault-tolerant controller and the corresponding trigger weight matrix is given via linear matrix inequalities. The reciprocally convex combination lemma and the improved Jensen integral inequality are employed to deal with the derivative terms of the Lyapunov-Krasovakii functional, which can reduce the conservatism and computation of the results. Finally, a simulation example is used to demonstrate the advantage and the effectiveness of the proposed co-design approach, meanwhile, the quantitative relationship between the system performance and the communication resources is provided.
