A secondary delay partitioning method is proposed to study the stability problem for a class of recurrent neural networks (RNNs) with time-varying delay. The total interval first divided into two parts, and then each part further several subintervals. To deal state variables associated these subintervals, an extended reciprocal convex combination approach double integral term variable upper lower limits as Lyapunov functional are proposed, which help obtain criterion. main feature result...

This article is concerned with average consensus of multi-agent systems via intermittent event-triggered strategy. First, a novel condition designed and the corresponding piecewise differential inequality for established. Using established inequality, several criteria on are obtained. Second, optimality has been investigated based consensus. The optimal strategy in sense Nash equilibrium local Hamilton-Jacobi-Bellman equation derived. Third, adaptive dynamic programming algorithm its neural...

This paper investigates the time-varying formation-tracking (TVFT) problem for multi-UAV systems (MUSs), where followers need to achieve a predefined formation configuration while tracking leader’s state. In order reduce consumption of communication resources, an adaptive event-triggered mechanism (AETM) is designed. By combining advantages technique and (ETM), UAVs can realize intermittent without relying on global information. Secondly, improve flexibility trajectories, TVFT consensus...

This article investigates the intermittent event-triggered optimal leader-following consensus for nonlinear multi-agent systems (MASs) utilizing actor-critic algorithm. First, we propose a novel distributed control strategy, and sufficient criterion is obtained to guarantee of MASs by establishing piecewise differential inequality. Next, strategy delicately given.

In this paper, we investigate the energy-efficient transmission problem by resource allocation in SCMA networks. We formulate it as an optimization to maximize network energy efficiency (EE) subject quality-of-service (QoS) requirements, codebook assignment, power allocation, and subcarrier reuse constraints. Due its mixed combinatory, separate assignment devise suboptimal but cost- efficient algorithms. With equally distributed, first propose a novel scheme assign codebooks. then develop...

In this article, the optimal leader-following consensus of nonlinear second-order delayed multiagent systems with input constraints is addressed. To begin with, a novel intermittent event-triggered (IET) control protocol proposed, and time-delay piecewise differential inequality established to effectively integrate state delay, control, strategy. Then, by proposed inequality, two criteria for its optimality under saturation are derived successively. Furthermore, constrained-input PI...

A new type of asymptotic stability for nonlinear hybrid neutral stochastic systems with constant delays was investigated recently, where the criteria depended on delays' sizes. Unfortunately, developed theory so far is not sufficient to deal challenging problems decay rate, time-varying delays, and nonautonomous issues. These have been tackled in existing literature. Consequently, under weak constraints, this article focuses general decay, including exponential polynomial stability, by...
