Concept:
Nyquist stability criterion:
N = P – Z
N is the number of encirclements of (-1+j0) point by the Nyquist contour in an anticlockwise direction.
P is the open-loop RHP poles
Z is the closed-loop RHP poles
Calculation:
Number of open loops RHP pole (P) = 1
Characteristic equation: 1 + G(s) H(s) = 0
⇒ s2 – 2s + 1 = 0
Number of open loops RHP pole (P) = 1
Characteristic equation: 1 + G(s) H(s) = 0
⇒ s2 – 2s + 1 = 0
⇒ s = 1, 1
Number of closed loop RHP poles (Z) = 2
From Nyquist stability condition,
Number of encirclements N = P – Z = 1 – 2 = -1
Therefore, the Nyquist plot encircles (–1, 0) once in the clockwise direction.
