| Abstract: | A three-dimensional continuous autonomous chaotic system was built, and the new system contains two quadratic cross-product term and three system parameters. Through the theoretical analysis, numerical simulation, Lyapunov exponent spectrum, and bifurcation diagrams, the basic dynamic property of the new system was studied. Furthermore, a digital circuit based on FPGA was designed for hardware implementation of the 3D attractors. The system simulations accorded with the experimental results. A new method for digital implementation of a chaotic system was proposed by using FPGA technology. |
