A new four-dimensional continuous-time autonomous hyperchaotic system is proposed in this paperwhich is built by adding a nonlinear controller to a three-dimensional continuous-time autonomous chaotic system. The hyperchaotic system is analyzed by studying the Lyapunov exponent spectrum and bifurcation diagram. The system will take on periodic and complex periodicchaotic and hyperchaotic behaviors with change of the parameter. Alsoan electronic circuit is designed and realizedthe experimental results verify the conclusions.
