1/8 DIN Controllers Combine Fuzzy and PID Control
For Fast Response to Process Disturbances
■ Advanced PID control for optimal response
during start-up and steady-state operation
■ Fuzzy and PID control work together to
correct a process upset quickly, with minimal
overshoot
■ Fuzzy parameters can be changed to adjust
fuzzy control's impact on the process
■ Accuracy to ±0.3% of set value
■ Field-selectable temperature ranges, °F/°C
scaling, and sensor input types
■ Plug-in outputs for field interchangeability
■ Communications function, heater burnout
alarm and 8-bank models available
■ 3-year warranty
Ordering Information
■ TEMPERATURE CONTROLLERS
Order one control output separately below. For example, E5EF-A02TC-F with E53-S SSR output unit. For heater burnout models, be
sure to order a current transformer. To order models marked for degrees Celsius, omit the "F" at the end of the part number.

Advanced PID Control Improved with Fuzzy Control
Omron's E5EF temperature controllers combine advanced PID
control with Fuzzy Logic control to improve responsiveness to
external process disturbances, events that cause a clear offset
between the process and set temperatures.
Omron's advanced PID control and Fuzzy Logic control operate
in parallel. The PID control operates during normal conditions,
while the Fuzzy Logic control operates only when there has
been an external disturbance to the process. The start-up and
stable state operation is identical to Omron's conventional PID
controllers. The output of the E5EF is the sum total of the
output of the PID and fuzzy control functions. Both PID and
fuzzy scale parameters can be set automatically by autotuning, or may be manually set.
There are three fuzzy parameters users can set, and the
illustrations show the impact of each one:
■ FUZZY INTENSITY
Fuzzy intensity (FU1) determines the impact of the Fuzzy
Logic section of the control algorithm, on the final control output
percentage. This parameter is the nominal value which can be
set from 0 to 99%. Default setting is 50%. When set to 0%,
fuzzy control will have no influence, and the unit will function as
a PID controller (like Omron's E5EX). As this value is
increased, the corrective actions taken by the controller will
become larger. The FU1 value should be increased in
applications where quicker neutralization of a process
disturbance is required, and/or overshoot on the recovery from
the disturbance needs to be further minimized.
Small
Fuzzy
intensity
Large
FUS1
Small
■ FUZZY SCALE 1
Fuzzy Scale 1 (FUS1) controls the magnitude of error
"membership function". This value corresponds to what the
controller should consider to be a "large" error and can be set
in a range of 0.2° to 999.9° (C or F). Default setting is 40°. For
every sample the controller compares the present error to
FUS1 value in order to make a subjective decision about the
size of the error. Decreasing this value makes the controller
more sensitive to error, and will decrease the response time for
returning the process back to set value.
Large
■ FUZZY SCALE 2
Large
FUS2
Small
Fuzzy Scale 2 (FUS2) controls the rate-of-change "membership function". This value corresponds to what the controller
should consider a "large" rate of change, and can be set in a
range from 0.20° to 99.9° (C or F) per second. For every
sample the controller compares the present rate-of-change to
the FUS2 value in order to make a subjective decision about
the size of the change. Decreasing this value will make the
controller more sensitive to change. Because small changes in
this value can cause a large increase in oscillations, best
results can usually be achieved by manually setting FU1 and
FUS1 and leaving FUS2 at the auto-tuned value.
