automatic voltage regulator

Sure!

You have a lot to learn, and not just about electronics. Like how to communicate. Care to give it another try? We're here to help.

Not bad... ;)

How about this:

He may need the isolated version:

If you take the knob off a variac, you can fit it with a pulley. A small gear motor can then turn the variac up and down. A meter-relay and a power relay can then control the power to the motor.

Generator? You're using a DC generator instead of an alternator? If it isn't a permanent magnet type, you'd just trim the output voltage by modulating the field coil current.

To make it AC, there's lots of designs out there: look into into "variable frequency controls" that drive AC motors, for examples, or "power inverter" like provide AC in automobiles if your needs are low-power.

You sound like the government...

I am so BUSTED!
