![This paragraph from the text defines the term "controllable".
The concept of rank plays an important role in the design of
engineering control systems, such as the space shuttle system
mentioned in this chapter's introductory example. A state-space
model of a control system includes a difference equation of the
form
xk+1 = Axk+ Buk for k = = 0, 1,...
(1)
where A is n xn, B is n xm, {x} is a sequence of "state vectors"
in R" that describe the state of the system at discrete times, and
{u} is a control, or input, sequence. The pair (A, B) is said to be
controllable if
rank B AB A² B
...
A"-¹B] = n
(2)
The matrix that appears in (2) is called the controllability matrix
for the system. If (A, B) is controllable, then the system can be
controlled, or driven from the state 0 to any specified state v (in
R") in at most n steps, simply by choosing an appropriate control
sequence in R"
Determine of the following matrix pair is controllable:
[0.9 1.0
