+ 
2 
u x2̇ 0 -2 x2 1 -

x1̇ 
= 
-1 0 

x1

x1 
+ 
1 
u x2̇ 0 -1 x2 0 -

x1̇ 
= 
0 0

Correct Option: A
| [A] = | ![]() | -1 | ![]() | , [B] = | ![]() | 2 | ![]() | ||||
| 0 | -2 | 1 |
Now, composite matrix,
| Qc = [B : AB] = | ![]() | ![]() | |||||
| then , det Qc = | ![]() | ![]() | ≠ 0 , | ||||
and rank = r = n = 2 and system is completely controllable.
