低频控制 meaning in Chinese

low frequency control

The multiresolution method is extended and applied to random vibration control system , thus a multiresolution random vibration control algorithm is created , which provides a satisfied solution to the poor control precision problem at low frequency that was pointed out and remained unsettled for many years . the control algorithm has been successfully implemented on dactron ' s shaker control system , showing great improvement in low frequency control precision , with a little more computation resource consumed . high resolution octave analysis is another successful application of multiresolution spectrum estimation theory
在多抽样率信号处理理论和多分辨谱估计理论的基础上，本文进而将多分辨率思想推广到随机振动控制理论中，提出了多分辨随机振动控制算法，解决了振动控制界多年来悬而未决的低频控制精度问题，并在dactron公司laser ~ ( tm )和comet ~ ( tm )等多种振动控制产品中得到了成功的应用，在计算量增加不大的前提下取得了令人满意的控制效果。
