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)

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.
