how can I make in Simulink ∫ dt?

Hi, how can I make in Simulink ∫ dt? In time domain, not Laplace domain.

Thank you:)

The whole concept of Simulink is time based simulation. You might be confused by the look of the blocks and the transfer functions are displayed like 1/s or 1/s-1 etc.

So just use the integrator block and you are fine.

I know that I can use 1/s but my teacher told me to not use 1/s. He said to me that I can find ∫ dt in Simulink Lybrary Browser. I have to simulate a DC motor. And one of blocks is (1/La)*∫ dt. Where La is known. Could you help me please?:)

[Andreas Goser]

I can't help with that. I can only speculate what your teacher might think. There are blocks that display the integral symbol, like the "Integrator Limited" block. You need to ask the teacher.

I asked today him and I can remember that he told me that I can replace 1/s with a MUX+I can't remember what other blocks. It's that possible?

[Andreas Goser]

I do not see any relationship between an integral operation and a signal infrastructure block. This is very confusing. Probably both of you call into Technical Support to sort out things together?

I spoke with my teacher and I'll use the 1/s block. Thank you very much for you support.
