LMI-based robust adaptive synchronization of FitzHugh-Nagumo neurons with unknown parameters under uncertain external electrical stimulation

► Dynamics of FHN neurons under uncertain stimulation current is provided. ► Synchronization control under uncertain stimulation current is developed. ► Robust adaptive control law under all unknown neural parameters is derived. ► LMI-based strategy is pursued to avoid controller parameter tuning effort. ► Adaptation law ensures precise estimation of stimulation current parameters.
