Consider a closed-loop system with unity feedback. For each G(s) hand sketch the Nyquist plot. Determine Z = P + N, algebraically find the closed-loop pole location, and show that the closed-loop pole location is consistent with the Nyquist plot calculation. K = 2.
a) KG(s) = 2(s-1)
b) KG(s) = 2(s+1)
c)KG(s) = 2/(s+1)
d) KG(s) = 2/(s-1)
