Paper Title:
Analysis of Wavelet Algorithm of Redundancy Denoising for Hydraulic System Signal
  Abstract

Based on the theory of Wavelet decomposing algorithm, in this paper an algorithm of redundancy real-time denoising is presented, and the test of on-line identification mode of a hydraulic cylinder’s work load pressure signals was fulfilled. This method can improve the stability of the signal collection and the control accuracy of hydraulic cylinder pressure effectively, solve the crawling phenomenon of hydraulic cylinder when working, and reduce the signal collection error resulted from the load mutation. By means of controlling the wavelet decomposing depth, the calculation amount of real-time denoising is controled, thus the optimization of the signal, damping vibration and denoising are achieved.
