Abstract
A method for recognizing a motor system is provided. The method includes steps of: establishing a functional series filter model for describing a motor system; generating a logarithmic sweep signal; feeding the logarithmic sweep signal to the motor system and obtaining, by an accelerometer, a vibration acceleration output by the motor system; generating an inverse signal of the logarithmic sweep signal generated; convolving the vibration acceleration with the inverse signal to obtain a one-dimensional impulse response sequence; intercepting the one-dimensional impulse response sequence by using a window function to obtain impulse response sequences; solving kernel functions according to the impulse response sequences, substituting the kernel functions into a recognition formula of the motor system, and describing and identifying the motor system through the recognition formula.
