MATLAB: How does this matlab function works

matlab functionss

If I give an input delay of 0.1350 to the state space system, it doesn't make any difference to the system's response
ss_model=ss(A,B,C,D,'InputDelay',0.1350)
Someone please explain how this function works or in what cases, this function fits in exactly.

Best Answer

This is not true
%-----------------model without delay-----------
A=[-11 1;-10 0];B=[0;1];C=[1 0];D=0;
ss_model1=ss(A,B,C,D)
subplot(2,1,1);
step(ss_model1)
%-----------------model wit delay----------------
retard=2
subplot(2,1,2);
ss_model2=ss(A,B,C,D,'InputDelay',retard)
step(ss_model2)
