Control theory - integrator?
<< < (3/5) > >>
rstofer:
Half way down the page here is a block diagram that clearly shows that 1/s is the integrator term because the input to the block is y' and the output is y

Block algebra is a systematic way to combine transfer functions of s  and here is a really good reference on the entire topic of control systems.  There is an entire section on Block Diagram Algebra.

We should keep in mind that nForce is a beginner trying to learn, and try to keep things a bit simpler.

Normally, Laplace transforms are introduced 2nd year, after calculus, and Fourier and DSP (if applicable) 3rd or 4th.

Given the question spans all four domains, and has a homeworky flavor to it -- I don't know how else to answer such a question. ???

If this truly is a beginner question, then, I've listed all the traditional prerequisites -- please, for the love of all that is good and electronic, study them, ruthlessly!

nForce:
If we have a derivative term it's the opposite of this?

Try to answer, my questions: "Yes, because..." or "No, because..."

Thanks.

The first four lines of your first post are more or less a statement of the Fundamental Theorem of Calculus, which states essentially that integration is the opposite of differentiation. If you look up this theorem you will find more discussion and explanation of this.
nForce:
Yes, I know the fundamental theorem of calculus.

If we start with integral term, then we get a derivative. If we start with the derivative term, then we are going to get an integral.
