Second Order Systems in Process Control

Second order systems may be underdamped (oscillate with a step input), critically damped, or overdamped. This lecture reviews theory and application of second order systems for process control. Second order systems are particularly useful to describe the closed loop response or underdamped mechanical systems.

Hi thank you very much for the video. How would I proceed with critically damped systems?

[kathlynjuaneza]

Hi! Can I know what book you're using? thanks in advance

Hi. Gret Video series.
I have seen people representing second order system with an equation having two time constant terms (t1 and t2). What are they exactly?

Thank you very much for this sir. Very helpful.

Hello I had an exam question on the same topic where G(s) = K * (s^2 +121)/(s^3+121s+4), but the poles are on RHS ( very close to Zero) and I was asked to trace the root locus and find values of K to make system stable and comment on the stabilty , over damped, under damped critcaly damped, oscillation.
Can someone help me please .

hi thank you sir for your video
please i have this equation
2*cos(x) - beta*sin(x) + beta*sin(alpha*x) = 0 with alpha and beta two parameters and i need to found x
what can i use for solving this equation
i first use Matlab with function solve but some one tell me to use inverse Lagrange theorem its look complicate for me ...
there is another alternative or something with Matlab to solve my equation?

is there a way to approximate zeta from the graph without doing any calculations? I ask this having attended a lecture in which the professor did just that, but I didn't get a chance to ask how they did it.

hello brother is this method(i.e at 21.15) know as damoing method?

[gerard-nagle]

Hi there, quick question, what text book do you use? Thanks

[lucasstefanelloferrarireme]

Hi, do you know the name of the method use to find the transfer function of the graph?

Why do some applications use omega and zeta instead of tau zeta?

Please can you make video on 2nd order System poles plots on pz-plane
And how to determine damping ratio and undamped natural from pz-plane ...

Sir, i wonder why u did not time the percent overshoot with 100??

[pnachtwey]

This is good but in reality it is hard to measure the peak or times accurately by just looking at a few points. This is OK if only rough estimates are required.
Edit, I just saw yet another video just like this one made at about the same time. The formulas looked the same and used the same variables. It was like both videos were copied out of the same book.
