When initiated, the controller will
start controlling to the setpoint while
it identifies the process, calculates
the tuning constants, and begins
TPSC control with the correct
tuning parameters.

Fuzzy Overshoot Suppression minimizes overshoot after a
setpoint change or a process disturbance.
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 TPSC algorithm, and the fuzzy logic
does not alter the TPSC tuning parameters.
This feature can be independently Enabled or Disabled as
required by the application to work with “TUNE” On-Demand
tuning.
