摘要
通过理论分析和实验验证,证明了采用同态滤波的方法识别机器扭矩载荷的可行性。同时提出了根据时序模型的Green函数来判定窗函数宽度的方法,减少了选取窗函数宽度的盲目性。作为应用实例,给出了采煤机扭矩的识别结果。
in this paper, the theoretical analysis and the experiments show that the load spectrum of amachine can be extracted from the output signal by homomorphic signal processing. A method ofdetermining 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 shearerdrum is described.
