摘要
本文提出了一种新算法,通过所述的准则可自动完成对采样数据的截取,从而减小甚至消除仪表中周期误差对通过积分求均值参数测量准确度的影响。论证表明,当采样和信号周期异步时该算法能自动补偿周期误差以提高测量结果的准确度;而同步时该算法则自动变成同步算法。计算仿真的结果验证了其有效性。
This paper proposes a new algorithm, called automatic compensation algorithm, to truncate automatically sampling data and to reduce or even to eliminate the influence of period -measurement error on measuring accuracy of parameters , which has the form of mean values by integration in sampling computation instruments. It has been proved that the new algorithm can automatically improve the measuring accuracy when the sampling is asynchronous, and the synchronous algorithm is only a special cause of presented algorithm in this paper. The validity of the new algorithm has been shown by simulations.
