| Abstract: | In this paper, an analysis on nonlinear dynamical system is conducted and base a mathematics model is setup. Then the model is applied to some physical system. According to the Liapunov exponent value, the reliability and performance of some methods in nonlinear problems are analyzed. As an attempt, these methods are tried to classify faults and give qualitafive prediction analysis of a system. The results show that these methods are successful in some extent. |
