Modulating Power supply

[fuzzzy]

Hi

I've a question.

I have to control V output from a Power supply using analog output from 0 to 5 V.
My problem is that Power supply can change. I always need to modulate it from minimum to maximum. Power supply can be: 12Vdc 24Vdc 36Vdc and 110Vac.

Is there a way to control these different output? Current flowing is little.
is there a component or a combination of compoinents that can control both DC and AC power supply?

thanks in advance.
