摘要
为了改善磁电式绝对振动传感器的固有缺陷,提出了一种基于回归算法的超低频绝对振动传感器传递函数优化技术,实验结果表明,该技术可有效地将绝对振动传感器的下限频率拓展1个数量级以上。
To improve the inherent low SNR limitation of the magneto-electric absolute vibration transducer, a transfer function optimizing technique for the ultra low frequency absolute vibration sensor was put forward based on the regressive algorithm. The experimental results show that it can expand the lower limit frequency of the absolute vibration sensor for more than one order.
