CD Convert Discrete to Discrete VI

Owning Palette: Model Conversion VIs

Requires: Control Design and Simulation Module

Changes the sampling time of a discrete-time system model. Wire data to the Discrete State-Space Model input to determine the polymorphic instance to use or manually select the instance.

CD Convert Discrete to Discrete (State-Space)

Prewarp Frequency (rad/s) is the frequency that this VI uses to produce a Tustin (bilinear) transformation with pre-warping. This VI only uses Prewarp Frequency (rad/s) when the Method is Prewarp.
Discrete State-Space Model is the discrete-time system model that this VI resamples with the new sampling time.
Resampling Time (s) is the time this VI uses to resample the input discrete-time model. The default is 1.
Method determines the conversion type this VI uses from discrete to continuous and continuous to discrete when resampling.

0Zero-Order-Hold (default)
1Tustin (Bilinear)
2Prewarp

4Backward
5Z-Transform
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Resampled State-Space Model is the modified discrete-time system model with the new sampling time. To access and modify the data in the model, use the Model Information VIs.
error out contains error information. This output provides standard error out functionality.

CD Convert Discrete to Discrete (Transfer Function)

Prewarp Frequency (rad/s) is the frequency that this VI uses to produce a Tustin (bilinear) transformation with pre-warping. This VI only uses Prewarp Frequency (rad/s) when the Method is Prewarp.

CD Convert Discrete to Discrete (Zero-Pole-Gain)

Prewarp Frequency (rad/s) is the frequency that this VI uses to produce a Tustin (bilinear) transformation with pre-warping. This VI only uses Prewarp Frequency (rad/s) when the Method is Prewarp.

CD Convert Discrete to Discrete Details

This VI supports time delays. In the conversion process, if the results of the delay conversion contain residues, this VI ignores the residues and gives a warning. Refer to the LabVIEW Control Design User Manual for more information about delays.
