“…Due to this property, chaos synchronization has been successfully applied in a variety of fields including secure communication, chemical and biological systems, human heartbeat regulation, information science, image processing, and harmonic oscillation generation [13,14]. Up to now, a wide variety of approaches have been proposed for synchronization of chaotic systems, such as adaptive control [8,13], impulsive control [15], fuzzy control [16], periodically intermittent control [17], observer-based control [18], and so on.…”
