SI Convert Discrete to Continuous Model VI

Owning Palette: Model Conversion VIs

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

Converts a discrete model to a continuous model. You can use this VI to convert discrete transfer function, state-space, and zero-pole-gain models to continuous transfer function, state-space, and zero-pole-gain models, respectively.

For an ARX, ARMAX, output-error, Box-Jenkins, or general-linear model, this VI converts the discrete model to a continuous transfer function model.

Example

	system model in contains information about the model structure, nominal or estimated parameters, identification result, and so on. Use the Model Management VIs to retrieve the information system model in contains. 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.
	tolerance determines zero-pole cancellations. If the difference between the location of a pole and a zero is within the tolerance, this VI removes the zero-pole pair. You can visually inspect the location difference in the pole-zero plot. The default is 1E-12.
	system model out returns information about the model structure, nominal or estimated parameters, identification result, and so on. Use the Model Management VIs to retrieve the information system model out contains. 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 out contains error information. This output provides standard error out functionality.
