阻抗参数的取样数值法测量

本文提出了一种利用阻抗电压、电流的同步取样数据，通过计算机数值处理来准确确定阻抗角，进而求得被测阻抗参数（ＲＬＣ）的新方法，它具有使用硬件少，计算简便，通用性强等特点，仿真结果表明了这种方法的可行性。

Sampling Numerical Method of Impedance Parameter Measurement

A new method for measuring impedance called sampling numerical method is presented in the paper.The two sampling data of the votlage and current of the impedance are obtained by means of synchronous sampling technique.And then,the impedance angle and parameter(RLC)can be obtained by using computer numerical analysis techniques.This method has the advantages of bearing generality and wanting less hardware and computatio.The practicability of the method is verified through simulation in the paper.
