SI Get Noise Covariance from System Model VI

Owning Palette: Model Management VIs

Requires: Advanced Signal Processing Toolkit or Control Design and Simulation Module

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.

Example

	system model contains information about the model structure, nominal or estimated parameters, identification result, and so on. Note  You can use a customized system model probe to view model information that flows through system model wires when you debug a block diagram created with the System Identification VIs. Right-click a system model wire and select Custom Probe»SI System Model from the shortcut menu to use the system model probe.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	noise variance returns the variance of the disturbance for a SISO or MISO system. noise variance returns –1 if system model contains a MIMO system.
	noise covariance returns the covariance of the disturbances for a MIMO system.
	error out contains error information. This output provides standard error out functionality.

Example

Refer to the Read Information from Model VI in the labview\examples\System Identification\Getting Started\General.llb for an example of using the SI Get Noise Covariance from System Model VI.
