Investigation on the Extended Angular-Velocity Vold-Kalman Order Tracking

Dynamic signals acquired from rotary machines can be characterized by the order tracking (OT) techniques. The extracted order components correspond to the operation of specific machine elements, and reflect their current healthy or faulty states. The study extends the angular-velocity Vold-Kalman OT scheme to simultaneously extract multiple order components. Theoretical derivation is illustrated with simulation of processing two synthetic signals to show its merit. Additionally, as an example to validate the effectiveness, the developed OT scheme is used to rank pass-by noise emitted from an electric scooter with CVT transmission system
