Vold-Kalman Order Filtering可以说是目前最好的谐波提取算法之一,印象中是BK的人提出来的,并商业应用在其分析仪器上。 很早以前的一个帖子对多种谐波提取算法做过一次比较,最终得出结论是Vold-Kalman Order Filtering最完美,NI在其振动声学工具包里用到基于Gabor变换的谐波提取技术,效果略差一点。 一直想把Vold-Kalm...
vold–kalman filtering公式详解vold–kalman filtering公式详解 Vold–Kalman filtering(沃尔德-卡尔曼滤波)公式可是个相当厉害的家伙!在咱深入了解它之前,先跟您唠唠我之前遇到的一件小事儿。 有一次,我参加一个学术研讨会,那场面,真是高手云集。我旁边坐着一位年轻的学者,看起来紧张又兴奋。在休息间隙,我们闲聊起来...
The Vold–Kalman Filter (VKF), a time-domain filtering technique, is here suggested as a fitting approach to extract condition indicators that characterize the condition of railway tracks and vehicle wheels. The proposed multi-order extraction scheme separates the deterministic (periodic) components ...
Vold-Kalman 滤波器由 Håvard Vold 和 Jan Leuridan 在 1993 年推出,能够使用已知频率向量从信号中提取非平稳周期分量 [1]。 在最小二乘法的意义上,它可以作为一个稀疏线性系统来解决。 与卡尔曼滤波器类似,VKF 基于结构方程和数据方程最小化成本函数。\n 本次提交实现了第二代 VKF,能够同时提取多个订单,...

In this paper, Vold-Kalman filtering order tracking (VKF-OT) and dynamic Bayesian network (DBN) are employed for the real-time rotor demagnetization detection from the torque ripple. First, a torque ripple model of the PMSM considering electromagnetic noise is proposed, and the torque variation ...

The use of Kalman filter methods for high-performance order tracking of noise and vibration signals was introduced in 1993. Based on experience with that original formulation, further work has produced significant enhancements which greatly extend the ability of these methods to deal with several pract...
