Abstract
This paper considers the fixed-time synchronization of multi-weighted complex networks (MWCNs) with /without coupling delays. Firstly, the problems of fixed-time average synchronization are solved for the MWCNs model without delays. A corresponding synchronization criterion is proposed as well. Secondly, the issues of fixed-time tracking synchronization of MWCNs with coupling delays are discussed. Some sufficient conditions are given to ensure the considered system achieve the synchronization goal. Thirdly, in contrast to the traditional fixed-time synchronization strategies containing many nonlinear control terms (Hu et al. in Neural Netw 89:74–83, 2017; Chen et al. in Neural Netw 123:412–419, 2020; Yang et al. in IEEE Trans Autom Control 62(11):5511–5521, 2017; Zhang et al. in IEEE Trans Cybern 49(8):3099–3104, 2018; Xu et al. in J Franklin Inst 355(1):164–176, 2018; Liu et al. in IEEE Trans Cybern 49(6):2398–2403, 2018), the new designed control protocols only contain fewer terms, which are economical just as claimed in Li et al. (IEEE Trans Cybern, 2020). Finally, two numerical examples are provided to show the effectiveness of proposed design.
