论文摘要
我们提出了一种有效的技术，可以通过脉冲作用在全球耦合集合中控制同步。我们假设我们可以观察集体振荡，并可以同时刺激合奏的所有元素。我们特别注意将干预措施最小化。关键思想是仅在最敏感的阶段刺激。为了找到此阶段，我们实现了自适应反馈控制。估计集体模式的瞬时相位，我们使用每个振荡周期的几个脉冲实现有效的抑制。我们讨论了神经科学结果的可能相关性，即开发用于深脑刺激的晚期算法，这是一种用于治疗帕金森氏病的医疗技术。
We present an efficient technique for control of synchrony in a globally coupled ensemble by pulsatile action. We assume that we can observe the collective oscillation and can stimulate all elements of the ensemble simultaneously. We pay special attention to the minimization of intervention into the system. The key idea is to stimulate only at the most sensitive phase. To find this phase we implement an adaptive feedback control. Estimating the instantaneous phase of the collective mode on the fly, we achieve efficient suppression using a few pulses per oscillatory cycle. We discuss the possible relevance of the results for neuroscience, namely for the development of advanced algorithms for deep brain stimulation, a medical technique used to treat Parkinson's disease.
