Frequency Domain Identification Improvements
Use the new algorithm to fit transfer functions to frequency domain data faster and more accurately using System Identification Toolbox™. To get a better fit for specific frequency ranges, you can specify built-in or custom weighting filters. The improved performance allows you to estimate transfer functions for multiple datasets more efficiently, especially for those with dynamics over a large range of frequencies.
