I have a control system with a PID controller, and im trying to simulate a system response, i need to plot the values first in a graph and then add the transfer function?
this is what i have found and im doing:
dt = 0.1; t = 0:dt:50; u = zeros(1,numel(t)); u(t<=20) = 45; u(t> 20 & t<=40) = -45; u(t> 40) = 0;
obviously with the lsim command
Is there a better way ?
Thanks in advance
