| Abstract: | This paper introduces wavelet analysis mathematics theory and its application in the roll eccentricity compensation control. The roll eccentricity signal is period-varied random one of rolling force,which is separated from complicated and high frequency signals. The system of roll mill press down is controlled to compensate the thickness variation of the hot strip mill so as to improve the hot-rolled strip thickness accuracy.In addition,the construction of the control system and the simulating results are also given in the paper. |
