构建了一类可切换的三维自治混沌系统,通过系统选择器实现这类系统间的切换.这类系统都由七项组成,且都包含三项系统变量乘积的二次非线性项.详细地分析了这类三维系统平衡点的性质、混沌吸引子的相图和Lyapunov指数等特性,设计了实现这类可切换系统的实际电路并进行了电路实验.
A class of switchable three-dimensional chaotic systems is built. These systems have seven terms on the right-hand side, three of which are quadratic nonlinear. Some of its basic dynamical properties are studied detailedly, such as the feature of equilibrium, the chaos attractor, Lyapunov exponent and fractal dimension. A practical circuit is designed to realize these systems.
