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,

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.
