How the of damping ratio zeta will vary of second order system when dc gain is minimized?
Are you referring to the DC gain of a closed-loop or an open-loop system?
Dear Pravin,
I suggest you to see links and attached files in subject or near, i hope you can found a solution for problem.

Dear Pravin,
I recommend you the next paper which is available in Researchgate. In the article the dependencies between the parameters of a second order differential equation are described.

One of the options is included. For details, see
