摘要

Wavelet analysis theory is a new theory developed in recent years. It is a new time-frequency localization methods. As its analyzing precision can be changed and focused to any detail of the analyzed signal,it is very useful to study nonstationary signals. In this paper, we mainly study the wavelet theory and its application to control system. Furthermore, we use it to detect the fault of underwater vehicle's navigation angle fault, and its simulation results are given at the end of the paper.
