Control System for Synchronization of Generalized Chua's Circuits in FPGA
Can Eroglu, F. Acar Savaci
In this study, feedback control system for synchronization of generalized Chua’s circuits has been implemented on Field Programmable Gate Array (FPGA). The feedback control rule has been derived by feedback linearization method. By feedback linearization, the coordinate transformation has been achieved then the control command for synchronizing generalized Chua’s circuits has been obtained. In order to implement designed synchronized system, Matlab Simulink design for generalized Chua’s circuits has been translated to Xilinx System Generator design to generate Very-High-Speed Integrated Circuits Hardware Description Language (VHDL) code which is used to produce bitstream file. By Xilinx Integrated Software Environment (ISE) program, VHDL code is converted to bitstream file which has been embedded into FPGA by Field Upgradeable Systems Environment (FUSE). Finally, synchronized generalized Chua’s circuits states and attractor have been observed on the HP 54540C oscilloscope.
