Note 3
Noninteracting Control
Noninteracting control suppresses mutual action between processes, and is
the same as feedforward control. Influence caused by mutual action is
regarded as disturbance, and is controlled by noninteracting control together
with feedforward control.
Function blocks used: Advanced PID (Block Model 012)
Lead/Delay (Block Model 147)
Note 4
Processing by which the value after lead/delay operation is subtracted from
other MVs is enabled by the MV compensation function of advanced PID.
