| Abstract: | The paper discusses sampling precise prediction and error correcting of drum lifting by memory program controlling, computation and analysis of the correlation degree of the reference sequence curve and the comparison of sequence curve by practice examples of sine function. The paper offers the study of several methods and the prediction of the character of the grey prediction correlation degree, combination of characteristic and demands of drum memory program control for shearers pursuing macroscopical and holistic following capacity, choice of the fit prediction methods of correlation degree. This method features practicability. |
