Constructing a Class of Four-Dimensional Correlative and Switchable Hyperchaotic Systems
A class of four-dimensional correlative and switchable hyperchaotic systems were built by adding state variables, nonlinear functions or using the method of anti-control the three-dimensional chaotic system. We studied detailedly some of its basic properties, such as the feature of equilibrium, the phase portraits of hyper chaotic attractor, Lyapunov exponent and the evolutive course of systemic dynamical action.
