To develop an automated condition monitoring and fault diagnosis method for induction machines using neural network modeling of vibration spectra.
Processed quasi-steady vibration signals into continuous spectra using the short-time Fourier transform (STFT).
Trained a neural network model to establish an analytical redundancy framework for an induction motor.
Identified machine faults by evaluating changes in the expectation of vibration spectra modeling errors.
Experimental results confirmed the neural network framework reliably detected and diagnosed machine faults from vibration spectra.
The analytical redundancy approach successfully adapted to the random characteristics of vibration signals, overcoming the limitations of conventional explicit motor models.
