Owning Palette: System Identification VIs

Requires: Advanced Signal Processing Toolkit or Control Design and Simulation Module. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Nonparametric Model Estimation VIs to estimate the impulse response or frequency response of an unknown, linear, time-invariant system from an input and corresponding output signal.

The VIs on this palette can return general LabVIEW error codes or specific System Identification error codes.

Palette ObjectDescription
SI Estimate Frequency ResponseEstimates the frequency response of an unknown system using the spectral analysis method. Wire data to the stimulus signal and response signal inputs to determine the polymorphic instance to use or manually select the instance.
SI Estimate Impulse ResponseEstimates the impulse response of an unknown system using the prewhitening-based correlation analysis method and the least squares method. You must manually select the polymorphic instance to use.
