PLC中利用Kahan算法作流量累积

Kahan's Summation Formula for Flow Accumulation in PLC

在工厂生产过程中,物质的流量总和常作为厂际间费用的结算依据。由于PLC的算法问题,导致其对浮点数处理方法存在一定的误差,为了克服这种缺陷,有必要找出一种更加精确的算法对流量进行累积。

In the process of factory production,the sum of material＇s flow is often used as the basis for settlement a- mong the plant.Because of the algorithm problem of PLC,there are some errors in the floating calculation.In order to over- come this problem,it is necessary to find a more accurate algorithm to accumulate the flow.
