摘　　要：构造了一个新的多涡卷三维连续自治混沌系统,该系统含有四个参数,三个非线性乘积项。通过耗散性分析、平衡点分析研究了系统的动力学性质,MATLAB仿真验证了系统的混沌特性,表明新系统能够产生四涡卷的混沌现象。采用运算放大器、模拟乘法器等常规元件,设计了该混沌系统的电路。电路仿真实验说明,构造的新多涡卷混沌系统具有混沌特性,丰富了混沌电路的设计与应用。A new three-dimensional continuous autonomous multi-scroll chaotic system is mtroaucea. ~ nc n^w ~y~ three cross-product nonlinear terms and four system parameters. The basic dynamic properties of the new system are investigated by means of dissipative analysis and equilibrium analysis. The chaotic properties are investigated by MATLAB simulation, and it is found that the system can produce chaos with 4-scroll. The chaotic circuit is designed using the operational amplifier, analog multiplier and other conventional components. The circuit implementation of this new system is simulated using EWB. The simu- lation results confirm that the chaotic system can be achieved.
