Research on Diesel Engine Signal Noise Reduction Based on Zero Space Tracking Algorithm

To reduce the noise interference of diesel engine vibration signals and extract useful information, a noise reduction method based on zero space-tracking algorithm is proposed in this paper. Using the adaptive decomposition characteristics of the zero space-tracking algorithm to denoise the signal. Compared with empirical mode decomposition and variational mode decomposition, this method is more suitable for the characteristics of diesel engine vibration signals. Simulation and example signals show that this method has achieved good noise reduction effects.
