Fault diagnosis system using vector quantization and its application to electromagnetic valve
Sheng Zhang, Toshiyuki ASAKURA, S. Hayashi · 2003
This paper is concerned with fault diagnosis using vector quantization of sound signals and its application to electromagnetic valves. Instead of establishing a mathematical model, the vector quantization directly extracts characteristic vectors from sample data by optimized algorithms and uses these characteristic vectors as standard patterns to make fault diagnosis. An application to electromagnetic valve verified the effectiveness of this new method.
