Problem 1. (Transformation to controllable canonical form) Consider the following third-order SISO LTI system:
x' = Ax + Bu
r ∈ ℳ, u ∈ ℹ
(A-BCLTI)
Assume that the characteristic polynomial of A is given by:
det(sI-A) = s³ + as² + a²s + a³
and consider the 3 x 3 matrix:
1 1 a²
T = C
0 1 0
0 0 1
where C is the system's controllability matrix.
a) Show that the following equality holds:
1 B = T
0
b) Show that the following equality holds:
-1 1 0
-a² 0 1
-3 0 0
AT = T
