Aiming to solve some existing problems and follow trends in fault detection and diagnosis, combined with new results obtained in relative disciplines, some kinds of schemes for dynamic systems are proposed in this dissertation.
1. A modified denoising method based on VC dimension and wavelet package is presented, improving the shortcomings of denoising methods based on empirical risk minimization and wavelets thresholds. Using FFT and wavelet package analysis theory, the abrupt faul...
