电机定子电流信号一般用电流霍尔检测，然后通过滤波器进行滤波得到。
The stator current is measured by using current whale, and then filtered.
这种方法通过滤波器组将信号分解与重构，实现趋向性信号与零均值平稳随机信号的分离。
Based on decomposition and reconstruction of the signals by filter sets, the trend-signal is separated from stationary stochastic signals.
最后通过滤波器加载输出腔的模拟计算结果与冷测结果的比较和分析，进一步验证该方法的可靠性。
Finally, a output cavity loaded with a filter is computed and the computed result is analyzed and compared with cold test data in order to conform the reliability of this simulated computation method.
