      Lenses

      A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

      What is in a lens?

      Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

      Who can create a lens?

      Any individual Connexions member, a community, or a respected organization.

Model Interconnection

Module by: Erik Luther

Model Interconnection Palette:

The VIs in this sub-palette can be used to connect different models in various configurations (i.e. Series, Parallel or Feedback mode).

Figure 1
Figure 1 (Graphic1.png)

The State Space and Transfer Function Model created previously are now connected in Series.

Figure 2
Figure 2 (Graphic2.png)

The above LabVIEW diagram creates the following system in block representation. Above, Model 1 is the state space model and Model 2 is the transfer function model.

Figure 3
Figure 3 (Graphic3.png)

This example also indicates the polymorphic nature of the functions. Note that the Polymorphic VI Selector at the bottom of the CD Series VI has changed to indicate SS and TF meaning that one of the inputs is a State Space Model and the other is a Transfer Function Model. LabVIEW performs this change automatically.

In the same manner, if you want to connect the Transfer Function Model in the feedback path of the State Space model, the function CD Feedback would be used.

Figure 4
Figure 4 (Graphic4.png)

The above LabVIEW diagram creates the following system in block representation. Above, Model 1 is the state space model and Model 2 is the transfer function model.

Figure 5
Figure 5 (Graphic5.png)

Note:

In this case, the order in which the models are connected is important. The model that is in the feedback path is connected to the second terminal (Model 2).

Thus, if we had to connect the State Space model in the feedback path of the Transfer Function Model, the input connections would need to be reversed.
