Dynamic Performance Extraction and Recognition of the PT Speed Governor Based on Mathematical Morphology
FUNCTIONAL MANUFACTURING AND MECHANICAL DYNAMICS II(2012)
Abstract
How to eliminate the noise effectively is always a difficult problem when detecting and recognizing the weak signal under complex electromagnetic environment. In order to improve the effect of denoising, the method based on the mathematical morphology was used. Base on the erosion and dilation operations of mathematical morphology, the correct extraction and recognition of dynamic performance of the PT speed governor was realized by the multi-mix operations of plus-minus and open-close, and the result provides a basis for the performance analysis and fault diagnosis of the PT speed governor.
