Abstract

This paper aims to propose an efficient algorithm for the synchronization of 4-D memristive chaotic systems and their applications for audio secure communication. A dual-function-link (DFL) fuzzy brain emotional controller (DFFBEC) is produced for synchronizing two types of 4-D memristive chaotic systems that are a 4-D hyperjerk memristive chaotic system and a 4-D memristive hyper-chaotic system. The proposed DFFBEC consists of three main networks that are a DFL network, a prefrontal cortex, and an amygdala. The gradient descent algorithm is used to derive the online learning laws for the proposed DFFBEC. Simulation studies of two 4-D memristive chaotic systems including external perturbations and non-deterministic perturbations, and an application for audio secure communication are studied to validate the capability and performance of the proposed DFFBEC. The results show that the proposed method can accommodate the system perturbation very well. Finally, the comparative results with some recent controllers and some other analytical results are used to illustrate the capability and performance of the proposed DFFBEC.
