1. Consider a plant that you want to control. The input u(t) and output y(t) of the
plant are related by
y(t) = 7 u(t) + w(t)
where w(t) is an additive disturbance at the output which is bounded by
-0.5 w(t) ≤0.5 for all time t. You want to build a controller so that the output
follows a constant reference signal r(t) = where -15 ≤≤ 15. You will consider
both open-loop and closed-loop for this problem.
a) Sketch the block diagram of the plant.
b) Please build an open-loop controller that sets the output to 7, assuming the
disturbance is ignored. Please show your controller both as an equation and a
block diagram.
c) Say that you use the open-loop controller in part b, but now the disturbance
w(t) is present. What is the maximum possible magnitude of error in the output
for the reference signal?
Suppose you have designed a feedback control for the plant where the controller
has the form u(t) = K(r(t) − y(t)). Here K is the gain constant of the controller
that you will design.
d) Please…
2. Suppose the Laplace transform of a causal signal x(t) is given by
s² +2
X(s) =
S³ + 1
Using the lookup tables for standard Laplace transforms and the Laplace transform
properties, find the Laplace transforms of the following signals. You do not need to
simplify the expressions.
a) x₁(t) = e² x(t) + 38(t − 1) − (t − 2)² u(t − 2)
b) x2(t) = x(2t - 1) + et u(t − 2)
