# How To Draw A Nyquist Plot

**How To Draw A Nyquist Plot** - Procedure to draw nyquist plot: R = wemodify the nyquist contour. Re g(s) in a new plane, call it c4 for closed loop stability, c4 should encircle ( 1=k; The pole/zero diagram determines the gross structure of the transfer function. If we detour to the left, then the poles count as unstable open loop poles.

Procedure to draw nyquist plot: Web a nyquist plot can be drawn using the following steps: If we detour to the left, then the poles count as unstable open loop poles. Can detour to the right or left. Gopal’s method states that you only need 4 points to be able to sketch the nyquist plot, and these points are [1],[2]: The nyquist plot can provide some information about the shape of the transfer function. And this is what it should look like:
