Abstract: This research work focuses upon the FPGA design and electronic circuit implementation of a new multistable four-dimensional hyperchaotic system. This work starts with the dynamics and phase plots of a new four-dimensional hyperchaos system. A detailed bifurcation analysis is carried out for the new hyperchaos system, and special properties such as multistability with coexisting attractors are reported for the new system. An electronic circuit model using MultiSim of the new hyperchaos system is designed. Finally, an FPGA-based design of the new hyperchaos system is performed by applying two numerical methods. Circuit simulation and FPGA design of the new hyperchaos system are very useful for practical applications of the new hyperchaos system.
Keywords: hyperchaos; hyperchaotic system; multistability; circuit simulation; FPGA design.
