You could get the ramp response by dividing your transfer function by s, and then taking the step response.
For example:
s = tf('s');
G = 1/(s+1);
figure
subplot(311), impulse(G); % Impulse reponse
subplot(312), step(G); % Step Response
subplot(313), step(G / s); % Ramp response

And then do some manual convolution

I don't think impulse(G*U) will work in matlab. I tried both these method but ans is different.

You can use lsim function for any input
t=0:0.1:10
alpha=2
ramp=alpha*t % Your input signal
model=tf(1,[1 20 3]); % Your transfer function
[y,t]=lsim(model,ramp,t)
plot(t,y)

%just define the tf and use step function to change the tf from T=1*G to
%T=1/s * G
s=tf('s');
T=(s^2+3*s)/ (s^2+7*s+6);
step(T/s)

Q --> Consider a system of the form shown in the figure in Problem 1. Let 𝐺(𝑠) = 𝐾 (𝑠+3) (𝑠+5) / 𝑠(𝑠+7) (𝑠+8)
1. a. What is the system type?
b. Consider 𝐾 = 1. On the same figure, plot the ramp input along with its response using lsim() command.
