研究了非线性耦合神经网络的有限时间同步问题，设计了一种新的开关钉扎控制器。对于固定的网络拓扑结构和控制强度，新设计的控制器可以通过调整参数α（0 ≤ α <; 1）来优化同步时间。本文所提出的控制律既包括连续控制器，也包括间断控制器。详细讨论了如何缩短强连通网络同步时间的一些准则。最后，将所得结果推广到任何含有有向生成树的网络拓扑，并通过一个数值例子验证了理论结果的有效性。
This paper is concerned with the finite-time synchronization issue of nonlinear coupled neural networks by designing a new switching pinning controller. For the fixed network topology and control strength, the newly designed controller could optimize the synchronization time by regulating a parameter α (0 ≤ α <; 1). The control law presented in this paper covers both continuous controllers and discontinuous ones, which were studied separately in the past. Some criteria are discussed in detail on how to shorten the synchronization time for the strongly connected networks. Finally, the results are generalized to any network topologies containing a directed spanning tree, and one numerical example is given to demonstrate the effectiveness of the theoretical results.
