Active magnetic bearings (AMB) vibration suppression: a breakthrough using adaptive filter with iterative search algorithm

After the ISA converges, the rotor vibration amplitude Vin is gradually reduced. in V drops from 11.74 um to 2.70 um, decreasing by 77.0%. Performing FFT analysis to the rotor displacement, the 1st ...

A study of recursive least squares (RLS) adaptive filter algorithm in noise removal from ECG signals

Abstract: Electrocardiogram (ECG) is a diagnostic procedure that measures and records the electrical activity of heart in detail. By reviewing an ECG report, one's condition of heart can be evaluated.
