5.20 Fuzzy Overshoot Suppression
Introduction
Fuzzy Overshoot Suppression minimizes overshoot after a setpoint change
or a process disturbance. This is especially useful in processes which
experience load changes or where even a small overshoot beyond the
setpoint may result in damage or lost product.
How it works
The fuzzy logic observes the speed and direction of the PV signal as it
approaches the setpoint and temporarily modifies the internal controller
response action as necessary to avoid an overshoot. There is no change to
the PID algorithm, and the fuzzy logic does not alter the PID tuning
parameters. This feature can be independently enabled or disabled, as
required by the application, to work with TUNE On-Demand tuning, the
SP tuning algorithm, or Adaptive Tune.
