  • The algorithm for the calculation of correlation dimension and Kolmogorov entropy was introduced.According to the analysis of chaos identity and the correlation dimension and Kolmogorov entropy of some engine,a new method of fault diagnosis that integrated correlation dimension with Kolmogorov entropy was proposed.The results show that the different fault has different correlation dimension and Kolmogorov entropy because of their different kinetics mechanisms,and thus correlation dimension and Kolmogorov entropy can be used to identify the fault symptoms.
