Fuzzy control
Description
Output takes either ON
(100%) or OFF (0%).
(Suitable when frequent
output switching is
inconvenient.)
Output is calculated with
PID parameters, outputting
0 to 100% with setting
proportional period (TC) as
100%.
Control with less overshoot
is available.
Fuzzy operation is added
to PID providing control
with less overshoot.
