(2) Description of auto-tuning parameters and how to set them
(a) RUN direction
RUN direction is to set the direction of auto-tuning run of a loop. The available option is forward
or reverse. The former (forward) means that PV increase when MV increases while the latter
(reverse) means PV decreases when MV increases. For instance, a heater is a kind of forward
direction system because PV (temperature) increases when output (heating) increases. A
refrigerator is a kind of reverse direction system in which PV (temperature) decreases when
output increases.
