Estimation Using Data from Frequency Response Estimator
Block
You can use the frestimate(data,freqs,units) syntax to perform offline estimation
with data from the Frequency Response Estimator block. In this case, frestimate uses
the Ready field of the data structure to determine which data points to include the FFT
computation of Resp.
- For sinestream mode, this signal indicates which periods to discard at each frequency,
determined by the Number of settling periods block parameter. - For superposition mode, this signal indicates which data falls within the data-
collection window determined by the Number of periods of the lowest frequency
used for estimation parameter.
frestimate interpolates Resp to generate the resulting frd model, which contains the
frequencies you specified in the block experiment parameters. For more information, see
the Frequency Response Estimator block reference page.
