称重传感器蠕变的模糊补偿方法研

以对传感器蠕变的一种新的补偿方法－－动态模糊补偿法，可实现蠕变实时精确补偿。引入模糊识别的方法来确定载荷的变化状况，利用传感器的输出变化率，判断传感器的蠕变起始点，从而确定作用于传感器上的实际载荷。同时这种方法的精度不受传感器的载荷与环境等影响，简单方便，易于计算机实现及批量生产，避免了繁琐的传感器蠕变模型的建立和实现过程，且精度较好，为传感器的蠕变误差补偿提供了一种崭新的方法。

Researches on Fuzzy Compen sation of creep of load cell

Creep is an important factor that influences the accuracy of a load cell. As one of the key specifications, it is also the most critical part for control. Based on the analysis of creep, a new compensation method--fuzzy creep compensation is presented in this paper. It firstly introduces the fuzzy recognition to determine the loading situations (i.e the rate of output change). The rate of output change will determine the start point of a creep segment of a loading/unloading curve, therefore, the actual load value could be gotten in the weighing process. Compare to other compensation techniques, it is, a new, simple, reliable and accurate compensation that not only avoids the complicated modeling of creep performance, but prevent from environmental influence as well.It is verified through experiments in the end.
