CD Verify MIMO Properties VI

Owning Palette: Model Information VIs

Installed With: Control Design and Simulation Module

Determines if the dimensions of the system matrices or transfer function matrix are consistent with the properties of the model variables, for example, delays and names. This VI calculates the number of inputs, outputs, and states (for state-space models only), and generates error messages for matrix dimensions that are inconsistent with the model. The data type you wire to the State-Space Model In input determines the polymorphic instance to use.

Use the pull-down menu to select an instance of this VI.

CD Verify MIMO Properties (State-Space)

State-Space Model In contains a mathematical representation of and information about the system for which this VI verifies the properties.
Required Matrices specifies the system matrices that this VI requires to continue execution.

error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs before this VI executes, the VI only closes the reference passed to it. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use exception control to treat what is normally an error as no error or to treat a warning as an error. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
If Static Gain Case? is TRUE, the system has a gain when the frequency is zero or when there is direct feedthrough between the input and output.
State-Space Model Out returns the model after this VI verifies dimensions and specification requirements. To access and modify the data in the model, use the Model Information VIs.
Number of States is the number of states based on system matrix dimensions.
Number of Inputs is the number of inputs based on model dimensions.
Number of Outputs is the number of outputs based on model dimensions.
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
