A room heater has a thermostat which senses room
temperature and turns the heater elements on or off, as
needed. It is close loop control.
A washing machine can have a closed loop feedback loop, for
example, water level, where a knob sets water level desired
[setpoint], a sensor detects level and turns off water
valve when satisfied. But the overall wash, soak, rinse,
empty, fill, spin functions are sequenced on a timed basis,
which is classic, open loop, non-feedback control.
Likewise a traffic light system can sense the presence of a
vehicle at an intersection, which enables an upcoming light
change, but the sequences of light changes are timer based,
open loop, non-feedback control.
