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.
|SI Estimate Frequency Response||Estimates 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 Response||Estimates 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.|
