Q128
A unity feedback control system is characterized by the open-loop transfer function G ( s ) = 10k ( s + 2 )s^3 + 3s^2 + 10. The Nyquist path and the corresponding Nyquist plot of G(s) are shown in the figure below. If 0 < k < 1, then the number of poles of the closed–loop transfer function that lie in the right-half of the s-plane is
