b) Find a state variable model (matrix form) for the system.
b) Determine state matrix, input matrix, and output matrix, when f (t) is defined as
the input and X2 is defined as output for the system.

Figure 4: A translational system
2. Consider a translational system shown in Fig. 4. Answer the following questions.
(a) Draw a linear graph and write down all the elemental equations. (Don't draw the normal
tree yet.)
(b) From the elemental equation you write down, identify three variables that can potentially
serve as state variables and explain why.
(c) Are these potential state variables independent of each other? If not, use either conti-
nuity or compatibility equation to prove it. How would you choose your state variables?
(d) Draw a normal tree to see if there is any dependent energy storage element. What are the
state variables according to your normal tree? Are they consistent with the explanation
in the Part (c)?
