Application of Homomorphic Signal Processing in Torque Load Indentification

In this paper, the theoretical analysis and the experiments show that the load spectrum of a machine can be extracted from the output signal by homomorphic signal processing. A method of determining the window width according to the Green function of a time series model is presented as well.So it is easier to choose the width in a limited range. As an example, the torque identification of a shearer drum is described.
