fuzzy controllers

I've done some reading about fuzzy controllers, and have run across a
general question I thought someone here may be able to provide insight,
pointers on.

It seems most of the fuzzy controller examples involve setting a machine
to the ideal setting. For instance, setting an air conditioner unit to
provide the best cooling. These settings only change when the
environment does. So the A/C setting would change when the sun came out,
etc.

Are fuzzy controllers used to control things that change throughout time
even given the same environment? For instance, an controller to make a
legged robot walk. Hand-designed controllers for these things are hard
to build, and typically involve a finite state machine approach.

So, I guess I'm wondering how fuzzy logic can been applied to controlling
time-varying processes.

Thanks!
