This paper presents a new hyper-chaotic system, which is obtained by adding a nonlinear controller to the third equation of the three-dimensional autonomous Chen-Lee chaotic system. Computer simulations demonstrated the hyper-chaotic dynamical behaviors o This paper presents a new hyper-chaotic system, which is obtained by adding a nonlinear controller to the third equation of the three-dimensional autonomous Chen-Lee chaotic system.
