I would want to know if someone has realized a PID algorithm (Proportional -
integral - derivative)
in order to control a motor DC through a microcontroller (x51 Family).
The motor are piloted by a PWM and has retraction with an analogic current
inputt.
If someone has realized it I would want to know which formula has used.
I have to disposition a T89C51AC2.
Thanks to all in advance payment

Way back I searched for the same thing (and did not have much luck)
You will probably do better to search for formulas for the individual
components that make up a PID
1. Proportional (simple gain)
2. Integral (low pass filter)
3. Derivative (high pass filter)

Once you find the formulas for these you should be able to combine them to
get the PID.
