Nyquist stability criterion
The closed loop system is stable if and only if the net number of anticlockwise encirclements of the point -1+j0 by the Nyquist plot of the system loop gain transfer function G(s) is equal to
the number of poles of G(s) in the right half-plane:
N(clockwise) = P.
the number of poles of G(s) in the right half-plane:
N(clockwise) = P.
