초록

Predicting the position and velocity pattern of particle flows in a hopper at industrial sites is an economicallyand temporally important technology. Simple kinematic theory can be used to predict when particles aredischarged from industrial silos. However, since simple kinematic theory does not take into account the influenceof the wall, more accurate prediction is possible only when additional corrections are made considering the walleffect. One of the feasible ways is to use the linearity of velocity error. However, the calibration using only thelinearity should be companied by the discontinuity of prediction. To solve this matter, the blending function isalso applied to this matter. Therefore, in this experiment, we propose a new approach considering both, linearityand blending function.
