ISE, IAE, ITAE via Simulink

I have the data for output y and time t taken from simulink into the matlab workspace. I also have plot of y versus t Error is defined as

e(t)= 1-y(t).

Is it possible to calculate Integral square error, Integral absolute error, Integral time absolute error from this information. How could I do it ?

[Nafees Ahamad]

trapz(t,abs(e)); % IAE trapz=numerical integration

trapz(t,e.^2); % ISE

trapz(t, t'.*abs(e)); % ITAE

trapz(t,t'.*(e.^2)); % ITSE

I am working on PI controller via matlab simulink, and want to assess the performance by using ISE . when i run the model i get a huge serise data of ISE in matlab workspace.

which value should be take as th ISE ??

Hi,

Last value can be taken.

try the below code.

ans.ISE.values(length(ans.ISE.values),1);
