2. The dynamics for the car Audi A2 (see Figure 2) is modelled by the standard state-space
representation
*(t) = Ax(t) +Bu(t)
y(t)
Cx(t) + Du(t)
with the following matrix values
[o
A =
D=
The above representation is obtained by allocating x1 (t) and x2(t) as the car's position
and velocity, respectively. Recall the input u(t) represents the propelling force produced
by the car's engine (in N). The output of the system is represented by y(t), which in this
case are the same as the states.
(a) Obtain the free response of the system y free(t) if the initial position is 0 m (x1(0) = 0)
and the initial velocity is 1 m/s (x2(0) = 1)
(b) Obtain the forced response of the system y forced (t) when the input is a step input
