Probably, unless it's specially designed for 400Hz; if there were such a
beast it would be a specialized aircraft relay from the 60's or 70's.
You could rectify the AC with a little bridge and use that to feed the
relay -- it should work well. Just what you need for a rectifier and
associated circuitry depends on whether the relay you use is mechanical
or not. For a mechanical relay there's a good chance that you could
just use a bridge and count on the relay coil's inductance to smooth the
current out sufficiently; for a solid-state relay you'd probably need a
bridge, filter capacitor and loading resistance.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.
