Controller design for fixed-time synchronization of nonlinear coupled Cohen-Grossberg neural networks with switching parameters and time-varying delays based on synchronization dynamics analysis

This paper addresses the fixed-time synchronization controller design problem for a class of nonlinear coupled Cohen-Grossberg neural networks (NCCGNNs) with switching parameters and time-varying delays based on synchronization dynamics analysis. First, a class of NCCGNNs with switching parameters and time-varying delays are considered. Second, according to the derived sufficient condition, a fixed-time synchronization controller is designed. Moreover, the advantages and disadvantages of the designed controller are discussed. Third, to improve the disadvantages of the obtained control method, by using synchronization dynamics analysis, some fixed-time synchronization controllers are further designed. Finally, two examples illustrate the usefulness and feasibility of the derived theoretical results.
