Controller design for FPGA-based chaos synchronization

The necessity of designing electronic chaotic oscillators separately for each chaotic system and design takes time, reveals the need for a new method. With the development of embedded system technology in recent years, the application of chaotic studies has become easier and more study can be done in a short time. In this study, Lorenz and Chen chaotic systems were synchronized under the same conditions and under the same initial conditions, using active sliding mode control and adaptive control methods. Then, in the Matlab / Simulink program, a chaos synchronization model was created and simulated. Finally, the chaos synchronization model was loaded into the Field Programmable Gate Array (FPGA) and real-time results were achieved thanks to the FPGA's Hardware Co-Simulation feature. Simulation results were compared with real time results, and the effects of active sliding mode control and adaptive control method on synchronizing system were compared. As a result, the real-time results of FPGA have been observed to overlap with the results of Matlab / Simulink simulation. It has also been observed that the FPGA provides easier, faster and more reliable results. In addition, it has been observed that the synchronized system with active sliding mode control method has less overshoot value and less settling time than the adaptive control method.
