“…Synchronization, a typical collective behaviour where by dynamical signals of chaotic systems tend to be identical with time elapsed due to a coupling or a forcing, not only can be observed in many physical systems like chemical reactions, power converters and biological systems [16,17], but also has been employed in a wide variety of engineering applications, such as information processing and secure communication [18]. Since the leading work of Pecora & Carroll [19], synchronization has been extensively studied and many effective methods for synchronization control have been exploited, including state feedback control [20][21][22], adaptive control [23], sliding mode control [24], impulsive control [7,13] and so on. In [21], both a feedback controller and an impulsive controller are designed to obtain the exponential synchronization for a class of discontinuous neural networks.…”
