A High Precision Glass Raw Material Burden System Controlled by Computer |
| |
Abstract: | This paper introduces a burden system for powdery glass raw material controlled by computer. The mechanical structure and circuit are designed for the demand of high precision. A compound filter technology that the RC low passing filter followed by the slide average filter is used in software and a predictive control algorithm is also used in the process of weighting. Because of the technology used above, the relative error of weighing has reached 0.1%. Furthermore, system block diagram and program flow chart are given. |
