摘要
本文以包装肥料称重系统的工艺流程为例阐述了应用PID+Smith预估补偿的方法克服在生产流程由于传动、机械等原因产生系统输出的滞后,从而减少称重系统的重量误差,大大提高系统输出的精度,使得误差控制在要求范围内。
This article provides an example showing how PID ＋Smith forecasting and estimating compensation is applied to the technological process of packing fertilizer weighing system. In this way,lagging of output system caused by gearing machine could be overcome. Furthermore, it could reduce weighing errors of the system and help improve the precision of output system .Using this way could make the error control within the range of demand.
