絮状物料的准静态计量装置

Quasi-static Weighing Device of Woolly Material

本文介绍了一种可以对连续、质轻的蓬松状物料进行准确计量和控制的准静态计量系统。详细论述了如何采用最优控制方法和软件编程技巧，将动态信号变为准静态进行在线计量。该仪器操作方便、修改参数灵活、抗干扰能力强，可以自动补偿系统误差和诊断外设故障，因此具有较高的实用和推广价值。

The paper introduces a kind of quasi-static weighing device .It can weighing and control woolly material which is carried continuously and mass of which is light. From theory to application, it discusses in detail how to use optimal control methods and software programming skill to measure on line, using the method which changes dynamic signals to quasi-static state ones. This instrument is convenient in operation, flexible in changing parameter and strong in anti- interference. It can compensate system error automatically and diagnosis periphery fault. So it has higher practical and popular value.
