Abstract To improve the dynamic weighing accuracy of powder in pneumatic conveying process, there was a dynamic weighing method based on extended Kalman filter algorithm be proposed, which set up multiple weighing sensors to fuse and filter the collected data, so as to eliminate the influence of interference noise on the system measurement. At the same time, the weight reduction measurement method was used to adjust the switching degree of the unloading control valve through the intelligent controller to improve the accuracy of dynamic weighing. The experimental results show that the average error of weighing 30kg silica powder is less than 0.3%.
