三电压法测量硅钢片比铁损的误差分析

Three-Voltage Measurement on Error Analysis of Silicon Steel Iorn Loss

通过分析信号源稳定度、样品制备工艺、采样误差等因素对硅钢片比铁损测量精度的影响,编制了Matlab下的数据处理程序和相应的GUI用户界面。在该界面下针对上述几种条件下的测量结果进行数据处理,得到了最佳测量条件,简化了传统三电压法测量中复杂计算问题,使测量周期大大缩短。

By analysis some factors that influence the measurement＇s accuracy,such as the stability of the signal source,the sample preparation process,the sampling error,also make a program based on Matlab and create a Graphical User Interface to analyse the figure from my experiment.Finally find the proper condition of this measurement.The use of GUI can Greatly simplify the complicated calculation process and shorten the computation time.
