i have plant g=1/(s^2+s+1) and i have fuzzy inference struct (fuzi) i need to simulate this system in m file like this (if i use pid ) c=pid(1,2); t=feedback(c*g,1); step(t) instead of c i need to use fuzi without using simulink only in m file

Hi,
I am afraid there is no easy way to do it. You would have to use evalfis to evaluate your fizzy logic controller at each computation step and then use something like ode45 to simulate plant step by step.
As you mention, Simulink would make this much easier.
