The integration block in matlab

Click For Summary

Discussion Overview

The discussion centers around the integration block in MATLAB's Simulink, specifically addressing the representation of integration in the Laplace domain and its implications for users new to MATLAB.

Discussion Character

  • Technical explanation

Main Points Raised

  • One participant expresses confusion about why the integration block in Simulink is represented by the symbol 1/s.
  • Another participant explains that the Laplace transform of the integral of a function is equal to 1/s times the Laplace transform of that function, indicating a relationship between time-domain integration and s-domain representation.
  • A third participant acknowledges the clarity provided by the explanation and asks a separate question about including mathematical formulas in forum posts.
  • A fourth participant provides a link to a thread that covers how to include mathematical formulas in posts.

Areas of Agreement / Disagreement

Participants do not express disagreement; however, the initial question remains open for further exploration regarding the integration block's representation.

Contextual Notes

The discussion does not address potential limitations or assumptions regarding the use of Laplace transforms or the specific context of the integration block in Simulink.

Who May Find This Useful

New MATLAB users, particularly those working with Simulink and interested in understanding the mathematical representations of integration.

I am new to matlab. There's a small thing that I am not aware of: why the integration block in simulink has the symbol as 1/s?
thanks for reading.
 
Physics news on Phys.org
The Laplace transform of [tex]\int_0^t f(\tau) d\tau[/tex] is equal to [tex]\frac{1}{s} F(s)[/tex], where F(s) is the Laplace transform of f(t). Thus integration in the time domain is equal to multiplication by [tex]\frac{1}{s}[/tex] in the s-domain.

Thank you las3riock. It's clear now.

(Another small question: how can you paste the formulas in the pages here? )
