摘要:

非线性动力学系统中的参数调制可以产生非周期非混沌的吸引子,即最大李雅普诺夫指数非正的吸引子。我们描述了一个程序,通过使用随机调制或伪随机二进制序列与任意长的递归时间来创建这样的吸引子。因此,吸引子是几何分形和运动是非周期性的实验可访问的时间尺度。这种吸引子的一个实际实现证明在实验中使用电子电路。

英文摘要:

Parametric modulation in nonlinear dynamical systems can give rise to attractors on which the dynamics is aperiodic and nonchaotic, namely with largest Lyapunov exponent being nonpositive. We describe a procedure for creating such attractors by using random modulation or pseudo-random binary sequences with arbitrarily long recurrence times. As a consequence the attractors are geometrically fractal and the motion is aperiodic on experimentally accessible timescales. A practical realization of such attractors is demonstrated in an experiment using electronic circuits.
