In order to overcome sensitive defects of components deviations and environment defects in
analog circuit design, a novel four-dimensional hyperchaotic systems is constructed based on Lü system.
Basic nonlinear dynamics characteristics are analyzed to the new system. By optimizing the design of
sampling frequency selection, gain adjustments, parameter configuration etc., the hyperchaotic circuit runs
stably while the signal amplitude is reasonably controlled. Curves of the digital chaotic sequence show
smooth without jagged shape. The circuit can be applied to other digital realization of chaotic systems with
commonality and expandability. Its experimental results fully consistent with phase space structures of the
continuous chaotic system, which shows the development of chaotic systems based on FPGA is feasible
and practical.
