i new in matlab.. my task to design a water level using PID controller and simulate using simulink.. this is my first try.. but i dont know how to use my coding with simulink..

clear all clc

syms s

%G=0.036/(36.942s^2+12.1568s+0.451)

num=0.036; den=sym2poly(36.942*s^2+12.1568*s+0.451);

G=tf(num,den);

H=1;

Kp=1; Ki=0; Kd=0;

C=pid(Kp,Ki,Kd);

T=feedback(C*G,H);

step(T)

after tune using pid tools.. i change it to kp=95 ki=3 kd=375

but i still dont know use simulink for this task..

you can use control system tool box of simulink to construct the pid controller.

Take a look at a few "getting started" videos for Simulink - you can find them here .

Also, check out videos and examples on PID Control with MATLAB and Simulink page.
