when I use Linear analysi tool to do Frequency response estimation to sweep input frequece from [10Hz 15K], It
takes more than 4 hours to get estsys1 data? even when my system 'a simple PFC block' is stopped, Linear analysis tool
still show 'Simulating the model' running, why?

Hi Jian,
频率响应估计可能很慢，特别是如果您使用的是电力因子校正等电力电子产品的SINESTREAM扰动信号。这可以取决于模型的采样时间等因素，估计的频率点数。最近我们推出了PRBS扰动信号，这导致估计时间更快，专门用于这种电力电子应用。与SINESTEAM信号相比，请看看您是否可以通过使用此信号获得良好的结果。拥有SINESTREAM结果可能是一个好的理智检查，以比较PRBS估计结果。
