I guess you could make a 4th order that also assumes the second order part was dominant. That would involve just adding an extra (s+p) onto the existing 3rd order equation. However you'd need to validate the assumption still.
But ts = 4 / zeta * wn is the settling time for an under damped System for 2% error band . How did you assume that the second order system (which is dominant) is an under damped system ?
You are told in the question to assume that the second order component is dominant. When designing second order systems, underdamped is generally the best type because it is able to achieve a quicker settling time than a critically damped or overdamped system (and you can usually tolerate the small amount of overshoot). The validity of the assumption is assessed at the end of the video.
@@theryderproject5053 Ok Thanks ! In India we need to give an entrance exam for pursuing Post Graduation from top Engineering Institutes like IITs and NITs . In the exam we usually find questions from Second Order Systems . Every year the syllabus is amended and minor changes are made . For 2021 exam , we have Third order Systems in our syllabus for Control Systems as well . This video came handy . Great video !
Very informative video. Bravo. My question is whether the same procedure would be followed if the system had one zero.
Thank you very much. I was finding this method desperately. You helped me a lot
Loved it
Saved my sanity!
Please what is the equation for rise time
Do you have a video on higher order systems? Im dealing with a 4th order system
If we have a 4th order characteristic equation instead of 3rd order, what would be the damping equation that we have to write??

thanks a lot
What is this method called?
I have Doubt that in 13>5 the second order assumption validation, why specifically 5
That's just the "rule of thumb". It isn't an exact science, but that's where the line has been drawn in the sand for making a decision about validity.
@@theryderproject5053 thank you very much
