| Abstract:As conventional noise removal methods were not able to meet the requirement of higher performance cross-directional basis weight control, a new method based on EMD was proposed. The method achieved noise removal by removing the high-frequency component and moving average filter based on time scale features and adaptability of EMD. The simulation results showed that the method had good noise removal effect. The gained data retained the main details of basis weight, which was conducive to subsequent control. |
