(7) The Nyquist plot of the open-loop frequency response of a unity feedback control system is shown below. Please answer the following two questions: (a) If the open-loop transfer function has one pole and no zeros in the right half s-plane, is the closed-loop system stable? (b) If the open-loop transfer function has one zero and no poles in the right half s-plane, is the closed-loop system stable? (a): @=∞ (b): @=0 Re

(7) The Nyquist plot of the open-loop frequency response of a unity feedback control system is shown below. Please answer the following two questions: (a) If the open-loop transfer function has one pole and no zeros in the right half s-plane, is the closed-loop system stable? (b) If the open-loop transfer function has one zero and no poles in the right half s-plane, is the closed-loop system stable? @=∞0 -1 (a): (b): Re @=0 (8) Manually draw a Nyquist plot for a unity feedback control system with the open-loop transfer function G(s) = K(1-s) (s+1) Using the Nyquist stability criterion, determine the stability of the closed-loop system. (Note: you need to show how you get your Nyquist plot by manually do the mapping. Using the Matlab/Control System toolbox to find your solution will not be accepted) Nyquist plot 7 j Im (G) Re(G) ∞
