“…Some sufficient conditions are established for CRDNNs to realize event-triggered passivity and synchronization. As is well-known, a large number of the traditional synchronization (Cao et al, 2008;Dharani et al, 2017;Tang et al, 2016;Wang and Wu, 2014;Wang et al, 2016Wang et al, , 2017aWang et al, , 2017cWu and Chen, 2008;Yang and Huang, 2017;Yang et al, 2013;Yu et al, 2019;Zhang and Gao, 2017) and passivity (Huang et al, 2018b(Huang et al, , 2019Li and Cao, 2016;Lin et al, 2018;Ren et al, 2017Ren et al, , 2018Wang et al, 2017b;Xu et al, 2016) results are derived for CNs. In contrast to those methods in above-mentioned works, the acquired results in our paper mainly rely on the triggering event mechanism, which can conquer the defects on a continuous method and decrease the redundant transmission of some communication media, especially when information is exchanging.…”
