为掌握动态测试系统的误差特性及传输特性，在全系统动态精度理论的基础上，提出了一种基于EMD和误差匹配相结合的方法。该方法首先采用EMD对动态测试系统的输出误差进行分解，然后根据分解结果进行误差匹配溯源。仿真结果表明，该方法能够有效地追溯到误差产生的源头，速度快，效率高，具有较强可行性和应用性。

To understand error properties and transmission properties of dynamic measurement system ,a new method was put forward by combining EMD with error matching based on the theory of whole system dynamic precision .Firstly,EMD was used to decompose the output error of dynamic measurement system ,and error matching was used to seek error sources according to the results of decomposition .Simulation results show that the method can trace error effectively with high speed and high efficiency .Therefore,it is highly feasible and applicable .
