code that do PID

[robota]

hellow friends
i look for code that do what the controller PID do
the code need to have 3 parts
pid = 1.proportional 2.integral 3.differential
i prefer in C language
where i can find this code
thanks

3.differential

to be more precise,,its Derivative ,,

anyways tell us what do you want to do and ll shoot ya the code
and how are you going to implement the PID

you should provide information about your system

if you are asking about theory then just google PID and youll get many good links

if you truly want PID, you must have a way of actually defining your setpoint and reading your PV.
for example, setting X position and speed of a motor, using an encoder, will require you to have a method of counting pulses and current position.

what are your values?

i know that my inglish is not perfect.
i don't asking about theory, i only asking about the code that do PID
the code need to do what the chip controller PID do without the chip
olso i need that the code will give me the optimal values for PID (who i do this task ?)
i look for code that do this tasks or do part of this tasks
thanks

 i can do that for u , just be specific on what u want
