CD Convert Delay with Pade Approximation VI
Owning Palette: Model Conversion VIs
Installed With: Control Design and Simulation Module
Incorporates time delays in a continuous-time system model using Pade approximation, which converts all residuals. The data type you wire to the State-Space Model input determines the polymorphic instance to use.
Use the pull-down menu to select an instance of this VI.

CD Convert Delay with Pade Approximation (State-Space)
 | State-Space Model In contains a mathematical representation of and information about the continuous-time system for which this VI incorporates time delays using Pade approximation. | ||||||
 | Polynomial Order is the order of the Pade approximation polynomials. The default value is 3. | ||||||
 | 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 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.
| ||||||
 | State-Space Model Out returns the system for which this VI incorporates the total time delay between each input-output pair into the transfer function between that pair using Pade approximation of Polynomial Order. To access and modify the data in the model, use the Model Information VIs. | ||||||
 | 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.
