How To Find a Point where Damping Line Crosses(intersects)Root Locus Mathematically :Control System

In this video lecture we will show how to find a point on the root locus mathematically where the damping line crosses the locus.how to find a point on root locus using mathematical approach.how to find a point where zeta line crosses root locus.how to find a point on root locus using angle and magnitude criteria.Finding point of intersection of root locus and damping ratio.

thank you for this broo

[@anismaliki3478]

This is really informative. Thank you sir. 😊

[@varijprajapati9562]

I got the way but It is more lengthy. Is there any other method which includes less calculation.

[@mwadood405]

Waiting to ur electronics and comm lecture 😊. Hope u wil do it soon

[@nordithen]

You write each sigma as a lowercase delta?

[@mwadood405]

Great effort sir 👌

[@TechSouls-wn6jc]

Waiting for more lectures in this section

[@basebetter3865]

hi ty for the solution,i tried to find the solution but the way that you taught did not work.the function was like this:K(s-2)(s-4)/(s^2+6s+25) there is k value in imaginary part and that is why i couldn't solve this problem.actually i cant find the sigma value.

[@umutosanmaz397]

I have same problem , I seperated as a imaginary and real part. But there is a K value in imaginary part.

[@engr.israrkhan]

darkness41 heaven in my example there is only k in numerator so i am getting only k in real part.in your example you have k(s-2)(s-4) in numerator so you have k both in real and in imiginary part .you have to put the value of w from equ1 into real and imiginary part then solve for k.i am trying to make another video related to your example.
