I am viewing your videos to catch up with something I had to learn years ago and I love it. Your in depth explanations motivate the subject just enough to get the viewer interested in the method itself rather than the "why do need this and how do I calculate it quickly" that is seen more frequently.

Thank you very much for your yet another insightful lecture. I always enjoy watching your lectures. Just a couple of side notes: @2:22 df/dt looks to be v_dot instead of dv (dv is df/dt times dt). Same happens with du=-s.exp(-s.t) @3:46. @4:20 the upper bound of exp(-s.t).f(t) is guaranteed to be zero only if f(t) is of an exponential type function ( |f(t)|

@antonnilukshan9353 ай бұрын
The physical systems usually take t=0 as the starting point so the 'one sided', and the stable systems by definition have to be stable so 'weighted' in order to introduce the negative gain along the timeline. Is that a correct way of generalizing the practicality of the Laplace transform in control systems theory? By the way, Thank you so much for this brilliant lecture Sir!

Shouldn't the Laplace tranform of f(t)=exp(at) be f_bar(s) = { 1/(s+a) if s>a, else -infinity }? You argue that gamma is chosen such that the boundary of the integral at infinity will always be zero, but gamma doesn't show up in these equations. Is it the case that we assume a

@anusmundianer Agree, your statement is more rigorous. Just one thing to mention here: in practice, the Laplace Transform that interests us is a Laplace Transform that converges. Therefore, if a Laplace Transform of a signal f(t) does not converge, it is usally of no practical use.
@jamma2464 жыл бұрын
Yes, he just assumed that f(t).exp(-st) converges to 0 as t -> infinity. That might depend on s, or it might not even happen for any s, if f(t) grows super-exponentially. So we're assuming here that f(t) doesn't grow too quickly, and then also that s is chosen large enough so that f(t).exp(-st) converges to 0 as t -> infinity.

quick question: COuld I "inverse transform" a Laplace transformation by recognition For instance i have an ODE the La place transform after all the algebra just looks like the La place transfrom of sine. I checked it three times "yup if i LT sin(2t) I get that" Could I just skip the inverse transform and say "yup the solution is sin(2t)" and only use the more complicated inverse transformation only if I don´t have something working in my tables?

Forgive me if im forgetting my math classes from years ago, but why do we treat s as a constant when we integrate? Isn’t it the variable of the laplace transform?
@carultch8 ай бұрын
s is a constant in the time domain, but it's a variable in its own domain. What you are doing with this transform, is scanning the original function as a superposition of exponential decay functions and sinusoidal oscillations. The s is the exponential decay rate when it is a real number, and frequency when it is an imaginary number. Or a multiplicative combination of the two behaviors, when it is a complex number. So if we fix frequency & decay rate, and integrate the function, we generate one piece of the information to find the transform. If we keep this as a variable, we get all possible results of integrating in the time domain, and put them together as a spectrum of amplitudes as a function of s. The Laplace transform result, is a spectrum in the s-domain.

What do you mean ‘we assume we multiplied this by e to the gamma t so this decays to zero’? We didn’t, f(t) is a positive exponential and we said the LT handles functions that don’t tend to zero at plus/minus infinity. You did ‘A Laplace’ on us there! I’m confused. Otherwise loving these lectures!
