But rest are right... appreciated your work...keep the spirit up

U solved question 2 incorrectly. Answer is around 3.5

[@chemelecturesbyrakeshkonku6027]

U can check the other comment discussion where I have provided the reason

Super

Sir, How can I solve that equation @video time 4.58 which you directly taken as 5.63 rad/min
Thanks in advance

Bro did you get it?

[@ankitbhimwal8107]

@@gloomyend1232 yea if you want to solve analytically hit and trial is the only option, but when that question is asked in the exam the type of calculator is provided we able to solve that equation.

please sir do live session

[@dhirajlaha4927]

Please anybody can give the detailed solution how phase crossover frequency was calculated it would be a great help if somebody can tell me

[@manassinha8623]

Solutions of first two questions don't match with the provided solution.

[@chemelecturesbyrakeshkonku6027]

Manas Sinha For the question no.1 I have taken measuring element as instantaneous..so order of closed loop process equal to order of open loop process.If measuring element is not instantaneous like first order etc then order of closed loop process is greater than open loop process ...

[@manassinha8623]

Thanks for the reply, now I understand where I was making mistake. Please tell me about the second question.

[@chemelecturesbyrakeshkonku6027]

Manas Sinha for question no.2 gain margin is defined at phase angle -180 degrees.so we can't use the frequency given at phase margin 30 degrees.
