Utilities VIs
Owning Palette: System Identification VIs
Installed With: System Identification Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Utilities VIs to perform miscellaneous tasks on data or the system model, including producing data samples, displaying model equations, merging models, and so on.
The VIs on this palette can return general LabVIEW error codes or specific system identification error codes.
| Palette Object | Description |
|---|---|
| SI Data Samples | Produces sample stimulus and response signals. You must manually select the polymorphic instance to use. |
| SI Draw Model | Displays model equations and the sampling rate in a picture indicator. You can use this VI to display the equations of a transfer function, state-space, zero-pole-gain, AR, ARX, ARMAX, output-error, Box-Jenkins, or general-linear model in a picture indicator according to the model representation you wire to the system model input. |
| SI Generate Pseudo-Random Binary Sequence | Generates a Pseudo-Random Binary Sequence (PRBS). |
| SI Get Continuous Transfer Function Denominator Information | Returns the denominator from a continuous transfer function model, including Tp, natural frequency, and damping ratio. |
| SI Merge Models | Merges multiple models of the same representation and order to one model. This VI supports only polynomial models. Wire system models to the system model 1 and system model 2 inputs to determine the polymorphic instance to use or manually select the instance. |
| SI Read from File | Reads arrays or waveforms from a specified data file. Use this VI to read spreadsheet text files and waveforms data files. |
