In this paper, global dissipativity and quasi-synchronization issues are investigated for the delayed neural networks with discontinuous activation functions. Under the framework of Filippov solutions, the existence and dissipativity of solutions can be guaranteed by the matrix measure approach and the new obtained generalized Halanay inequalities. Then, for the discontinuous master-response systems with parameter mismatches, quasi-synchronization criteria are obtained by using feedback control. Furthermore, when the proper approximate functions are selected, the complete synchronization can be discussed as a special case that two systems are identical. Numerical simulations on the chaotic systems are presented to demonstrate the effectiveness of the theoretical results.
本文研究了具有不连续激活函数的时滞神经网络的全局耗散性和准同步问题。在 Filippov 解的框架下,通过矩阵测度方法和新得到的广义 Halanay 不等式,可以保证解的存在性和耗散性。然后,对于具有参数失配的不连续主从系统,通过反馈控制得到准同步判据。此外,当选择适当的近似函数时,可以将完全同步作为两个系统完全相同的特例进行讨论。通过对混沌系统的数值仿真,验证了理论结果的有效性。
