I want to use a PID controller to regulate the position of a servo motor, and the "computer " of this machine is a microcontroller. But is it possible not to use a servo drive, as long as I calculate the transfer function, couldn't I just let the microcontroller do the servo drives job, and let it use the plant to regulate the voltage and current?

If you have a way to commutate the motor and receive position feedback from it, you could write your own PID loop to position it. You can usually get a fairly cheap drive for DC brush servos, brushless are a little more money. If it's an AC servo, I'd just buy a drive.
If you 're talking about a servo similar to what you would see in a remote controlled vehicle, those are also easy to control.
