We show that the recently introduced 0-1 test can successfully distinguish between strange nonchaotic attractors (SNAs) and periodic/quasiperiodic/chaotic attractors, by suitably choosing the arbitrary parameter associated with the translation variables in terms of the golden mean number which avoids resonance with the quasiperiodic force. We further characterize the transition from quasiperiodic to chaotic motion via SNAs in terms of the 0-1 test. We demonstrate that the test helps to detect different dynamical transitions to SNAs from quasiperiodic attractor or the transitions from SNAs to chaos. We illustrate the performance of the 0-1 test in detecting transitions to SNAs in quasiperiodically forced logistic map, cubic map, and Duffing oscillator.
我们表明,通过适当选择与翻译变量相关的任意参数(基于避免与准周期力共振的黄金分割数),最近引入的 0-1 测试可以成功区分奇异非混沌吸引子 (SNA) 和周期/准周期/混沌吸引子。我们进一步通过 0-1 测试来描述从准周期运动到 SNA 的过渡。我们证明该测试有助于检测到从准周期吸引子到 SNA 的不同动力学过渡,或者从 SNA 到混沌的过渡。我们说明了 0-1 测试在检测准周期强迫 logistic 映射、立方映射和 Duffing 振荡器中的 SNA 过渡中的性能。
