Design of a fuzzy sliding-mode synchronization controller for two different chaos systems

This investigation presents a fuzzy sliding-mode technology for synchronizing two chaotic systems. A method of designing a fuzzy sliding-mode control (FSMC) is presented, which utilizes a variable normalization factor. FSMC is designed to guarantee the global asymptotic synchronization of state trajectories of two different chaotic systems. The chaotic systems are numerically simulated to demonstrate the validity and feasibility of the proposed control structure. (C) 2010 Elsevier Ltd. All rights reserved.
