| Abstract: | In this paper, a new method based on Hough transform of automatic sampling frequency of the latter and the concept of eigencircularity are proposed, and are applied to fault diagnosis of a rotating machinery, it shows that this method has a number of advantages, such as distinguishing the fault signal, increasing the inner space between the fault signals, good stabability and correcting the inner of network system indentification. To sample frequency of the latter is automatically realized by this method. |
