摘　　要：构造了一个新的混沌系统,并对该系统的耗散性、平衡点的稳定性、Lyapunov指数和分岔图等基本动力学特性进行了分析.通过计算机仿真观察到了该系统的混沌现象,设计了实现该系统模拟电路,并提出一种确定此类电路元件参数的计算方法.电路实验结果与动力学特性分析、数值仿真完全相符,验证了系统的混沌行为.This paper constructs a novel chaotic system,and basic dynamic properties of the new system are analyzed using the dissipative property,stability of its equilibrium points,Lyapunov exponent spectrum and bifurcation diagram,etc.Chaotic behaviors of this system are observed by numerical simulations.Finally,an electronic circuit is designed to realize the new chaotic system,and calculating method for determining this type of circuit parameters.Experimental chaotic behaviors of the system are found to be identical to the dynamic properties predicted by theoretical analysis and numerical simulations
