Help in Identifying Simulink Block

Hello everyone,

I need help in identifying this Simulink block in the link below. I can't seem to find it in any of the Simulink blocks. It could be a custom block but I don't know which or where to start creating it. Can anyone point me to the right direction?

Thanks!

Answer 1

[Pedro Villena]

Maybe:

• tansig - Hyperbolic tangent sigmoid transfer function
• elliotsig - Elliot symmetric sigmoid transfer function
• Lookup Tables

[Joshua Jorel Lee]

Thank you! However, where can I find the elliotsig block?

[Andreas Goser]

Elliotsig is part of Neural Network Toolbox, but looks different (has an "E" top right corner)

[Joshua Jorel Lee]

Thanks! But most likely, I'll be using the tansig function. Thanks!

Looks like the Saturation block in (standard) Simulink. In the Discontinuities sub library.

[Joshua Jorel Lee]

Thank you for your input. However, I don't think it's the saturation block since the edges are curved instead of straight. I tried resizing that block if it would give me a curved signal icon effect but to no avail.

[Andreas Goser]

I was thinking you only have a screenshot... If you HAVE the block in a model, then this is easy: Click the context menu and select help and the documenentation of the block will open.

[Joshua Jorel Lee]

I was experimenting on the different blocks in Simulink, I tried resizing the saturation block if it would look like the block I'm looking for but unfortunately, it's not it. I only have an image of that block from a thesis document, in which I'm trying to recreate. But thanks for the tips though! I'm new to Simulink and I'm currently doing this for my thesis.

[Andreas Goser]

Got it now. It maybe clear from the context of the screenshot of a larger portion of the model.

Going by the characteristics plotted in figure, I think it is a 'Hystresis' block.

If you are working electrical domain, then I think below link would be useful:

Hope it helps!!!
