Good day to you people,
I have just started learning control theory at Uni, as part of my course, and I have to admit it is quite difficult to grasp.
I am starting from the basics, and I am having difficulty understanding what 's' is supposed to represent as regards the Laplace transform.
for example:
L{f(t)} = F(s)
Now to me these variables represent the following:
L - as in Laplace transform of a
f - function of
t - time
is equal to
F - Laplace function of
s - ??
I am slightly confusing it with Dynamics and Statics I think, where 's' refers to displacement. And so I am naming that as something I am aware of.
My guessing is that the 's' is referring to the s-plane as a complex plane, but still that is a difficult concept to grasp.
Can anyone give me some sort of analogy or point me at a resource that might be able to help a student understand this concept and it's relationship to the poles of a system.
Sorry for giving such a vague post, but I don't know how to narrow this down any more at the moment.
Kind regards
Rob
