摘要
构造了一个新的分数阶混沌系统,该系统含有5个参数,2个非线性乘积项,通过理论推导、数值仿真、Lya-punov指数谱分析了系统的动力学性质,验证了系统的混沌特性,描述了该系统的整数阶和分数阶混沌状态,发现新系统出现混沌的最低阶数仅为0.3.
A new system with integer and fractional order is introduced.The new system contains two quadratic cross-product terms and five system parameters.The basic dynamic properties of the new system are investigated via theoretical analysis,numerical simulation,and Lyapunov exponent spectrum.And it is found that the lowest order producing chaos is 0.3.
