Question
A feedback control system has the following parameters:
G(s) =
K(s+2)
s(s+1)(s+3)
and
s+6
H(s)
s+7
(Unless stated, assume that G(s) is the plant or in the forward path, and H(s) is in the feedback path).
What is the characteristic equation of the system? Expand the polynomial.
0 = <polynomial expression>
Answer:
=
Complete the R-H table:
821
S7
Note that some entries are functions of K. Put zeros on blank spaces. Do not leave a space blank.
What is the range of K for which the system is stable?
-106.67 < K
K<-42.15
-6.64 < K
0<K
The system is not stable for any value of K.
None of the above
