4. Answer the following questions. Take help from ChatGPT to answer these questions
(if you need). But write the answers briefly using your own words with no more than
two sentences and make sure you check whether ChatGPT is giving you the
appropriate answers in our context.
A) What is the zero-input response?
B) What is the zero-state response?
C) What are pole, zero, and residue in the context of our class?
D) What are the different methods for finding the inverse Laplace transform?
Which one we used in this class?
3. You have come to encounter an LTI system. You have no idea how the system
behaves. So, you decide to drive the system with a particular input and measure the
output. When you put the input u(t) = et 1(t), you find that the output y(t) =
(1-e) 1(t). You can assume zero initial conditions. Now, find the transfer
function of the system.
1. Consider the following LTI system.
d²y
dy
du
+7
+6y=
--
+2u,
t≥0
dt²
dt
dt
a) What is the impulse response of the system? Recall, h(t) = L-¹(H(s)).
b) What are poles and zeros of the system?
c) Suppose the initial condition of the system is y(0) = 1 and y'(0) = 4. What
is the zero-input response of the system?
d) Consider an input u(t) = (1 + et) 1(t) to the system. What is the zero-state
response of the system for this input?
e) Suppose, the initial condition was y(0) = -2 and y'(0) = -8 and the input is
u(t)=(1+e) 1(t). What will be the total response of the system? You
should be able to answer this using the linearity property of the system and your
answers in part b and part c without taking any inverse Laplace transform.

The inertia matrix is given by I = [125 0 0; 0 100 0; 0 0 75] which is a diagonal, where diag operator provides a matrix with given elements placed on its diagonal. Consider three cases where the body rotates 1 rad/sec about each principal axis. Integrate the resulting motion and study the angular rates and the resulting attitude (use any attitude coordinates). For each principal axis case, assume first that a pure spin about the principal axis is performed, and then repeat the simulation where a small 0.1 rad/sec motion is present about another principal axis.
