Abstract :
In this paper, we proposed the FPGA implementation of complete synchronization methodology for a novel chaotic systems using adaptive control scheme. Chaotic systems are non linear dynamical system having at least one positive Lyapunov exponents. In this paper, first we derived a new adaptive controller and parameter update law to synchronize the identical novel chaotic system using adaptive control theory and Lyapunov stability theorem. Then the novel chaotic system, adaptive controllers and the synchronized chaotic system are implemented in FPGA vertex 6 using Xilinx System Generator technology. After implementation, the RTL schematic diagram, the source consumed by the novel chaotic system and the synchronized systems are obtained. The Isim smulation results are also given to show the effectiveness of our proposed synchronization methodology.
