提出了一种产生多翼蝴蝶混沌吸引子的新方法.基于三维Lorenz系统,通过增加一个状态变量和一个分段线性函数,构造出一个四维多翼混沌系统.分析了系统的平衡点和Lyapunov指数谱.最后,设计出一个模拟电路,进行了电路实验.电路实验结果与数值仿真结果相一致,验证了该方法的可行性和有效性.%A new method to generate multi-wing butterfly chaotic attractors is presented. Based on the three-dimensional Lorenz system, in this paper we propose a four-dimensional multi-wing chaotic system by appending a state variable and a piecewise linear function. The equilibrium points and Lyapunov exponent spectra of the system are studied. Furthermore, an electronic circuit is designed to implement the system. The experimental results are in agreement with numerical simulation results, which verify the feasibility and availability of this method.
