Feature extraction of coal mine ventilator vibration signals based on improved variational mode decomposition
The vibration signal of coal mine ventilator is a non-stationary multicomponent signal. Traditional methods for feature extraction of non-stationary signals suffer from poor adaptability and limited ability to identify weak characteristics of early faults in the ventilators. Additionally, the signal...
