This article focuses on event-triggered quasi-synchronization in discrete Markov jump neural networks (MJNNs). By introducing a hidden Markov model, the mode mismatches in real-world applications are described. A more general event-triggered protocol is constructed by developing the threshold parameter as a diagonal matrix to achieve a desired balance between synchronization performance and event-triggered transmission. The sufficient condition for event-triggered quasi-synchronization of MJNNs is proposed using Lyapunov techniques, and a tighter error bound is obtained through an iterative algorithm and linear matrix inequality. A numerical example is provided to demonstrate the effectiveness of the control scheme by comparing the conservatism between the proposed approach and the existing one.
This article is concerned with the event-triggered quasi-synchronization for discrete Markov jump neural networks (MJNNs). Considering that the slave system cannot capture synchronously master system modes in real-world applications, a hidden Markov model is introduced to describe the resultant mode mismatches. To pursue a desired balance between the synchronization performance and the event-triggered transmission, a more general event-triggered protocol is constructed by developing the threshold parameter as a diagonal matrix. Subsequently, the sufficient condition for event-triggered quasi-synchronization of MJNNs is proposed with the assistance of Lyapunov techniques. Moreover, resorting to an iterative algorithm and the linear matrix inequality, the tighter error bound is obtained. Finally, a numerical example demonstrates effectiveness of the control scheme via a comparison of conservatism between the proposed approach and the existing one.
