A Double Function-Link Function-Based Fuzzy Brain Emotional Controller for Synchronizing a 4D Hyper-Chaotic System

This research poses a double function-link fuzzy brain emotional controller (DFLFBC) to synchronize a 4D hyper-chaotic system. The DFLFBC contains three main structures and a set of fuzzy inference rules. Three main structures are comprised of a double function-link network, an amygdala, and a prefrontal cortex. The double function-link is employed for adjusting the output weights for the prefrontal cortex and amygdala branches. The online learning laws for the proposed approach to online adjust the parameters are derived from the gradient descent algorithm. Synchronization studies of a 4D hyper-chaotic system are implemented to check the capability and performance of the DFLFBC.
