Model Conversion VIs
Owning Palette: Control Design VIs and Functions
Installed With: Control Design and Simulation Module. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Model Conversion VIs to convert a system model from one representation to another, from a continuous-time to a discrete-time model, or from a discrete-time to a continuous-time model. You also can use the Model Conversion VIs to convert a control design model into a simulation model or a simulation model into a control design model.
The VIs on this palette can return general LabVIEW error codes or specific control design error codes.
| Palette Object | Description |
|---|---|
| CD Convert Continuous to Discrete | Converts a continuous-time model to a discrete-time model using the Sampling Time (s) and the Method you specify. The Zero-Order-Hold conversion method supports input and output delays that are not an integer multiple of the Sampling Time (s). The data type you wire to the Continuous State-Space Model input determines the polymorphic instance to use. |
| CD Convert Control Design to Simulation | Converts a control design model into a model you can use for simulation. The data type you wire to the State-Space Model input determines the polymorphic instance to use. |
| CD Convert Delay to Poles at Origin | Incorporates delays into discrete system models by adding poles at the origin to account for the specified delay. The data type you wire to the State-Space Model input determines the polymorphic instance to use. |
| CD Convert Delay with Pade Approximation | 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. |
| CD Convert Discrete to Continuous | Converts a discrete-time model to a continuous-time model by using the specified Method. The data type you wire to the Discrete State-Space Model input determines the polymorphic instance to use. |
| CD Convert Discrete to Discrete | Changes the sampling time of a discrete-time system model. The data type you wire to the Discrete State-Space Model input determines the polymorphic instance to use. |
| CD Convert Simulation to Control Design | Converts a simulation model into a model you can use for control design. You must manually select the polymorphic instance to use. |
| CD Convert to State-Space Model | Converts a system model to state-space form. This VI produces a full or minimum realization by specifying the Realization Type. The data type you wire to the Transfer Function Model input determines the polymorphic instance to use. |
| CD Convert to Transfer Function Model | Converts a system model to transfer function form. The data type you wire to the State-Space Model input determines the polymorphic instance to use. |
| CD Convert to Zero-Pole-Gain Model | Converts a system model to zero-pole-gain form. The data type you wire to the State-Space Model input determines the polymorphic instance to use. |
