Parameterized Instantaneous Frequency Estimation Method for Vibration Signal with Nonlinear Frequency Modulation
The vibration signal from the rotatory machinery condition monitoring under time-varying speed is usually amplitude-modulated (AM) and frequency-modulated (FM). It is important to efficiently and accurately estimate the instantaneous frequency (IF) of the vibration signal. In this paper, a novel par...
