摘要
在三阶Qi系统的基础上,构造了一个具有两个较大正的Lyapunov指数和较大参数范围新的超混沌系统,分析了该系统的平衡点及稳定性,Lyapunov指数谱和分形维数,超混沌吸引子的相图等特性,并利无量纲状态方程的模块化设计方法实现了该系统,实验结果与仿真结果完全一致。
A novel hypderchaotic system based on three order Qi system is proposed and constructed,of which the two positive Lyapunov exponents are fairly bigger while the parameter range is relatively wider.Some of its basic dynamical properties are studied in detail,including equilibrium and stabilily,Lyapunov exponent specturm and fractional dimension,the phase portraits of hyperchaotic attractor.The system is implemented with modular design method of nondimensional state equation.Experiment result is quite consistent with simulation resalt.
