3. The Vold-Kalman filter 3.1. The process and measurement equations Given a realization of a discrete-time, noise-corrupted ABA stochastic process, the Wold decomposition reads [59], (5)y[k]=x[k]+η[k]where k∈Z+, t=kTs (s) are the associated discrete time indices for a given equ...
Vold-Kalman filterEnergy entropyReal-time chatter detection is important in improving the surface quality of workpieces in milling. Since the process from stable cutting to chatter is characterized by the progressive variation of the vibration energy distribution, entropy has been utilized to capture ...

This paper presents a simplified simulation model of electrical rotating machinery and an experimental test rig for applying the Vold-Kalman filter order tracking technique (VKF-OT). The effectiveness and advantages of VKF-OT for condition monitoring are demonstrated on both the simulation model and ...
The Vold-Kalman filter allows for the high performance simultaneous tracking of orders in systems with multiple independent axles. The interactions associated with close and crossing orders give rise to beating and complex psychoacoustic phenomena. With this new filter and using multiple tachometer referen...
