how find ramp response

what is method to find out ramp response of a transfer system.......... there is any command like step or impulse?

Find the time response for the system G(s)=1/s+19 for unit r amp input

Answer 1

[Teja Muppirala]

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

[Azzi Abdelmalek]

% or more general:

out=impulse(G*U)  % G your transfer function
                  % U the Laplace transform of your input signal

[Louis Lee]

And then do some manual convolution

[Akash Vyas]

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

Answer 2

[Azzi Abdelmalek]

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)

what is alpha

Answer 4

how to get a ramp response from s^2+3s/ s^2+7s+6

[Ibrahim Baza]

%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)

Answer 6

[Nadir Alsabaey]

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.
