Synchronisation of quaternion-valued neural networks with neutral delay and discrete delay via aperiodic intermittent control

This paper studies the synchronisation of quaternion-valued neural networks with neutral delay and discrete delay by aperiodic intermittent control. By using inequality techniques and constructing appropriate Lyapunov–Krasovskii functional, a main criterion expressed as quaternion-valued linear matrix inequalities is derived to pledge the synchronisation of the considered quaternion-valued neural networks. The theoretical result is demonstrated by an illustrated example as well as simulations.
