Quasi-Synchronization for Complex-Valued Neural Networks with Leakage Delay and Mixed Delay

Recently, quasi-synchronization, a special dynamic behavior, has emerged as a new hot topic of neural networks (NNs). In order to complete and expand the content of quasi-synchronous theory, complex-valued neural network (CVNNs) should be considered to investigate, which is more complicated and has enriched performance. In this paper, the problem of quasi-synchronization of CVNNs with leakage delay and mixed delay is discussed. Based on separating techniques, two equivalent real-valued systems are obtained for further study. Then, utilizing Lyapunov function and novel proposed controller, several quasi-synchronization criteria of CVNNs are established. Finally, numerical simulation results are given to show the validity of our theoretical results.
