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 Frequency-Domain Model Estimation VIs to estimate the frequency response function (FRF) and to identify a transfer function (TF) or a state-space (SS) model of an unknown system.
The VIs on this palette can return general LabVIEW error codes or specific System Identification error codes.
| Palette Object | Description |
|---|---|
| SI Estimate FRF | Estimates the frequency response function (FRF) of an unknown system. Use the FRF to estimate a transfer function (TF) model or a state-space (SS) model of the system. |
| SI Estimate State-Space Model from FRF | Estimates the parameters of a discrete state-space model for an unknown system by using a frequency response function (FRF). Wire data to the FRF magnitude and FRF phase inputs to determine the polymorphic instance to use or manually select the instance. |
| SI Estimate Transfer Function Model from FRF | Estimates the parameters of a continuous or discrete transfer function (TF) model for an unknown system by using a frequency response function (FRF). You must manually select the polymorphic instance to use. |
