What does polar plot represent?

The polar plot representation is the graphical representation of Y(jω). The polar plot is obtained as the locus of the real and imaginary parts of Y(jω) in the polar plane. The coordinates of the polar plot are the real and imaginary parts of Y(jω).

How do you plot a polar plot?

To plot a point in the polar coordinate system, start with the angle. If the angle is positive, then measure the angle from the polar axis in a counterclockwise direction. If it is negative, then measure it clockwise. If the value of r r is positive, move that distance along the terminal ray of the angle.

How stability is determined from polar plot?

Stability using Polar Plot

1) If (–1,0) is left of the polar plot or (–1,0) is not enclosed by it then closed loop system is stable. Here closed loop system is corresponding to the open loop transfer function for which the polar plot is sketched.
