settling periods to wait at each frequency, and the number of periods to use for estimation. To ensure that the experiment runs long enough for a good result, thestart/stopsignal stops the experiment att= 180. For details about the recommended experiment length, seeFrequency Response Estimator. ...
Post simulation, the logged input and output signals are processed to compute a frequency response of the model. Online frequency response estimation The frequency response of a physical plant is estimated during real-time operation with the Frequency Response Estimator block. This blocks injects ...
You can use thefrestimate(data,freqs,units)syntax to perform offline estimation with data from theFrequency Response Estimatorblock. In this case,frestimateuses theReadyfield of the data structure to determine which data points to include the FFT computation ofResp. ...
The frequency-response model that results when you use a sinestream input contains all the frequencies in the sinestream signal You can use a sinestream input signal for estimation at the command line, in the Model Linearizer, or with the Frequency Response Estimator block. The estimation ...
This MATLAB function estimates a matrix of frequency response functions, frf, from the excitation signals, x, and the response signals, y, all sampled at a rate fs.
