Yes. And it helps to make the "dead band" fairly wide so that the next
correction is delayed. Another aid is to have the correction response a bit
sluggish ie use slow motor/ gearing combo. It's even acceptable in some
control systems to have these continuously acting ie never satisfied.
Generator voltage regulators fall into this category.  Cheers..ALEC
