CD Get Data from Model VI
Owning Palette: Model Information VIs
Requires: Control Design and Simulation Module
Obtains data that describes the dynamics of the given system model. Wire data to the State-Space Model input to determine the polymorphic instance to use or manually select the instance.
CD Get Data from Model (State-Space)

![]() |
State-Space Model contains a mathematical representation of and information about a linear time-invariant (LTI) system for which this VI returns data. |
![]() |
error in describes error conditions that occur before this node runs. This input provides standard error in functionality. |
![]() |
Matrix A returns the system matrix that describes the dynamics of the states of the system. |
![]() |
Matrix B returns the input matrix of the system that relates the inputs to the states. |
![]() |
Matrix C returns the output matrix that relates the outputs to the states. |
![]() |
Matrix D returns the transmission matrix that relates the inputs to the outputs. |
![]() |
error out contains error information. This output provides standard error out functionality. |
CD Get Data from Model (Transfer Function)

![]() |
Transfer Function Model contains a mathematical representation of and information about a linear time-invariant system for which this VI returns data. |
![]() |
Output (row) specifies the output, or row, number of the transfer function in which this VI retrieves the data. This number is necessary when the model represents a MIMO system. The default value is zero. |
![]() |
Input (column) specifies the index number of the input column of the transfer function in which this VI retrieves the data. This number is necessary when the model represents a MIMO system. The index is zero-based. The default is zero. |
![]() |
error in describes error conditions that occur before this node runs. This input provides standard error in functionality. |
![]() |
Numerator returns the numerator of the transfer function as Output (row) and Input (column) specify. |
![]() |
Denominator returns the denominator of the transfer function as Output (row) and Input (column) specify. |
![]() |
Delay returns the transport time delay between the Output (row) and Input (column) pair. |
![]() |
error out contains error information. This output provides standard error out functionality. |
CD Get Data from Model (Zero-Pole-Gain)

![]() |
Zero-Pole-Gain Model contains a mathematical representation of and information about a linear time-invariant system for which this VI returns data. |
![]() |
Output (row) specifies the output, or row, number of the transfer function (in zero-pole-gain form) in which this VI returns data. This number is necessary when the model represents a MIMO system. The index is zero-based. The default value is zero. |
![]() |
Input (column) specifies the index number of the input column of the transfer function (in zero-pole-gain form) in which this VI returns data. This number is necessary when the model represents a MIMO system. The index is zero-based. The default is zero. |
![]() |
error in describes error conditions that occur before this node runs. This input provides standard error in functionality. |
![]() |
Zeros returns the zeros of the SISO system as Output (row) and Input (column) specify. |
![]() |
Poles returns the poles of the SISO system as Output (row) and Input (column) specify. |
![]() |
Gain returns the scalar gain of the SISO system as Output (row) and Input (column) specify. |
![]() |
Delay returns the transport time delay between the Output (row) and Input (column) pair. |
![]() |
error out contains error information. This output provides standard error out functionality. |
