Model Management 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 Model Management VIs to access information about the system model. Model information includes properties such as the system type, sampling rate, system dimensions, noise covariance, and so on.
The VIs on this palette can return general LabVIEW error codes or specific system identification error codes.
| Palette Object | Description |
|---|---|
| SI Check System Model | Verifies whether the data dimensions are consistent with the model parameters in system model. |
| SI Create System Model | Creates a model for an unknown system. |
| SI Get Coefficients from System Model | Returns the coefficients of system model and the standard deviation and covariance of the coefficients. Use the SI Set Coefficients to System Model VI to apply coefficients and the standard deviation and covariance of the coefficients to system model. You must manually select the polymorphic instance to use. |
| SI Get Delays from System Model | Returns the delay from the system model. You must manually select the polymorphic instance to use. |
| SI Get Dimensions of System Model | Obtains the number of inputs and outputs for a system model. |
| SI Get Names from System Model | Reads input and output names from a system model. Use the SI Set Names to System Model VI to write input and output names to a system model. |
| SI Get Noise Covariance from System Model | Obtains noise variance and noise covariance from a system model. Use the SI Set Noise Covariance to System Model VI to apply noise variance and noise covariance to a system model. |
| SI Get Notes from System Model | Reads comments from a system model. Use the SI Set Notes to System Model VI to write comments to a system model. |
| SI Get Orders of System Model | Obtains the orders of a system model. You must manually select the polymorphic instance to use. |
| SI Get Sampling Rate from System Model | Retrieves the sampling rate of a discrete system model. Use the SI Set Sampling Rate to System Model VI to apply a sampling rate to a system model. |
| SI Get Static Gains from System Model | Returns the static gain from a system model. The system model you wire to the system model input determines the polymorphic instance to use. |
| SI Get Type of System Model | Reads the model type from system model. The number of inputs and outputs of the model determines its system type. |
| SI Load System Model from File | Loads a system model from a .sim file. A .sim file is a system identification model file that saves all model coefficients regardless of the model type. Use the SI Save System Model to File VI to save a system model to a .sim file. |
| SI Save System Model to File | Saves a system model to a .sim file. A .sim file is a system identification model file that saves all model coefficients regardless of the model type. Use the SI Load System Model from File VI to load a system model from a .sim file. |
| SI Set Coefficients to System Model | Applies coefficients and the standard deviation and covariance of the coefficients to system model. Use the SI Get Coefficients to System Model VI to return the coefficients and the standard deviation and covariance of the coefficients of system model. You must manually select the polymorphic instance to use. |
| SI Set Names to System Model | Writes input and output names to a system model. Use the SI Get Names from System Model VI to read input and output names from a system model. |
| SI Set Noise Covariance to System Model | Applies noise variance and noise covariance to a system model. Use the SI Get Noise Covariance from System Model VI to obtain the noise variance and noise covariance from a system model. |
| SI Set Notes to System Model | Writes comments to a system model. Use the SI Get Notes from System Model VI to read comments from a system model. |
| SI Set Sampling Rate to System Model | Applies a sampling rate to a system model. Use the SI Get Sampling Rate from System Model VI to retrieve the sampling rate from a system model. |
