PID controller without using Simulink

Hello everyone!

Is it possible to create a PID controller on Matlab without using Simulink?

I'd like to set up a PID controller in a throttle valve present in a water system, but without using Simulink.

Can anybody help me, please?

Thank you

"doc pid" or look at the examples in "doc connect"

Thank you for your suggestion, but I didn't find any example referred only to the use on Matlab and NOT on Simulink.

Run this. It's all in MATLAB, no Simulink.

C = pid(2,1); 
C.u = 'e';  
C.y = 'u';
G = zpk([],[-1,-1],1);
G.u = 'u';  
G.y = 'y';
Sum = sumblk('e = r - y');
T = connect(G,C,Sum,'r','y');
step(T);
