| Abstract: | In this paper, the Application of phase space reconstruction technique in Hydraulic Pump Fault Diagnosis are expounded. Industrial systems typically exhibit nonlinear behavior when failure or fault occurs. The correlation dimension can be used quantitatively describe the phase space property of the attractor for the quality of reconstruction. In this research, the principle of selecting time delay and embedding dimension was studied. GP algorithm to compute the correlation dimension is relative ease with which it can be calculated from a measured time series of dynamic system. |
