A New Four-Wing Hyperchaotic System and Its Circuit Implementation Based on FPGA
Weifeng Zhao · Journal of Southwest University · 2013
Based on a three-dimensional chaotic system,this paper constructs a novel four-wing hyprchaotic system by adding a state variable.Some basic dynamical properties of the system are studied,including its phase diagrams,equilibrium points and Lyapunov exponent spectrum.Based on IEEE-754 standard,the circuit of the hyperchaotic system is designed by FPGA,and the results of physical experiments are in agreement with those of numerical simulations,which verifies that the system is realizable.
