Lenses

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

What is in a lens?

Lens makers point to 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 member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

This content is ...

Analyzing Dynamic Characteristics

Module by: Erik Luther. E-mail the author

Dynamic Characteristics Palette:

The VIs found here are used to find the dynamic properties of a system (i.e. Root Locus, DC Gain, Time Response Parametric Data, etc).

Figure 1
Figure 1 (Graphic1.png)

The most frequently used VI of this sub-palette is CD Root Locus. This VI plots the trajectory of closed loop poles as the feedback gain varies from zero to infinity.

CD Root Locus.vi:

Figure 2
Figure 2 (Graphic2.png)

This function gives the Root Locus plot of a system. This polymorphic VI accepts any model as an input, including Transfer Function, State-Space or Pole-Zero-Gain models. The indicator for this VI is created in the same fashion as that for CD Nyquist, and the grid type can only be changed from the Block Diagram.

Figure 3
Figure 3 (Graphic3.png)

The Root Locus plot in the Front Panel is shown here. This function also plots the Evans plot or trajectory of closed-loop poles.

DC Gain.vi:

This VI calculates the DC Gain of the system.

Figure 5

The DC Gain of the system is shown in the Front Panel.
