摘要
利用时延反馈控制噪声诱导的相位共振振子。具体来说，在适当选择时延后，可增加或减少运动的规律性。证明在可激发系统中，延迟反馈可稳定振荡频率以抵抗噪声强度的变化。此外，对于固定的噪声强度，延迟反馈可引起基本振荡周期的诱导。通过改变时延，此现象允许控制噪声诱导运动的时间尺度。

4 pages, 4 figures. In the replacement file Fig. 2 and Fig. 4(b),(d) were amended. The reason is numerical error found, that affected the quantitative estimates of correlation time, but did not affect the main message
