The open-loop transfer function G(s)H(s) of a system has one pole in the right-half of the s-plane. If the Nyquist plot of G(s)H(s) encircles the critical point (-1, j0) once in the counter-clockwise direction, then the closed-loop system is:
- 1Always stable✓
- 2Unstable with one closed-loop right hand pole
- 3Unstable with two closed-loop right hand poles
- 4Unstable with three closed-loop right hand poles
