A system is described by the state equation
Ẋ = AX + BU.
The output is given by Y = CX,where, A = -4 -1 , B = 1 , C = [ 1 0 ] 3 -1 1
Transfer function G(s) of the system is
-
-
s s2 + 5s + 7
-
1 s2 + 5s + 7
-
s s2 + 3s + 2
-
1 s2 + 3s + 2
-
Correct Option: A
Transfer function G
G(s) = C(sI – A)– 1 B
(sI - A) = | s | - | -4 | -1 | = | s + 4 | ||||||||||||||
0 | s | 3 | -1 | -3 | s + 1 |
Here , G(s) = | s + 1 | 1 | ||||||||||
s2 + 5s + 7 | +3 | s + 4 | 1 |
= | ||
s2 + 5s + 7 |
