In this paper, a new hyperchaotic system is presented by adding a nonlinear controller to the three-dimensional autonomous chaotic system The generated hyperchaotic system undergoes hyperchaos. chaos, and some different periodic orbits with control parameters changed The complex dynamic behaviors are verified by means of Lyapunov exponent spectrum, bifurcation analysis, phase portraits and circuit realization. The Multisim results of the hyperchaotic circuit were well agreed with the simulation results (C) 2009 Elsevier B V. All rights reserved
