This problem is related to Problem 6.9 in the Nise text.
Determine whether the unity feedback system is stable when G(s) is:
G(s) = 160 (s^4 + 4s^3 + s^2 + s + 6)
R(s)
G(s)
C(s)
The closed-loop transfer function is C(s)/R(s).
The Routh-Hurwitz table is:
s^4 |
s^3 | s^2 |
s^2 | 1 |
Is the given system stable?
