FPGA Based Digital Implementation of Adaptive Synchronization Methodology for 6-D Chaotic System

In this paper, we proposed the FPGA based digital implementation of synchronization methodology for 6-D chaotic systems via nonlinear feedback adaptive control technique.We derived new results for the adaptive controllers and the parameter update laws based on Lyapunov stability theory to achieve the synchronization between identical 6-D chaotic systems.Since the digitization of chaotic synchronization is necessary for digital communication, the proposed adaptive synchronization methodology is implemented in digital circuits based on Field Programmable Gate Array chip.The digital chaotic signal also generated using MATLAB simulink and Xilinx System Generator technology.The numerical simulation and FPGA outputs are used to prove the robustness and effectiveness of our proposed methodology.
