摘　　要：在经典单涡卷colpitts混沌系统基础上,引入基于双曲函数的非线性函数,构建了一个能够产生多涡卷吸引子的新型混沌系统。Matlab数值仿真结果表明,该系统可以获得更复杂的多涡卷混沌吸引子;改变系统参数,可以实现系统在周期与混沌轨道中运行,具有丰富的动力学特性。Based on the classic single-scroll colpitts chaotic system,by introducing nonlinear functions based on hyperbolic functions,a new chaotic system is constructed which can generate multi-scroll chaotic attractors.The numerical simulation results based on matlab confirm that the system can obtain more complex multi-scroll chaotic attractors.By changing the parameters,the system can be transformed in cycles and chaotic orbits and it has rich dynamic characteristics.

关 键 词：colpitts混沌电路 多涡卷吸引子 非线性函数
