Báo Cáo A study on decision tree for induction motor diagnostic system

ABSTRACT
​

A Decision Tree based on the vibration analysis for induction motor is proposed to diagnose the
motor status. Decision Tree is an expert system that builds the knowledge-based system from
experiences and itself can play the role of a diagnosis tool. Vibration signals are collected from
induction motor and processed to become inputs of the tree. From these input data, the tree will
perform tests to give the final diagnostic result that shows the motor status. The paper also reviews the
main problems of induction motor, and describes the abnormal frequency components in the machine
fault induced vibration spectrum.

Keywords: Decision Tree, expert system, induction motor, diagnosis, vibration signal.
