Loop Controllers with
Fully Integrated Sequence and Loop Control and Built-in Gradient Algorithm
for Uniform Temperature Control Across Multiple Points
Inconsistent thermal processing temperatures
result in unstable workpieces and reduced yield.
OMRON's unique Gradient Temperature Control
technology enables uniform in-plain control of thermal processing
temperatures. This not only increases the quality of thermal processing,
but also reduces energy loss while the temperature stabilizes and the
adjustment time required to eliminate interference caused by heaters.
This has a great impact on batch ovens,
glass substrate hot plates, and other precise process control.

What is
Gradient Temperature Control? |
|
Gradient temperature control enables
controlling the temperature of an object subject to interference at
multiple points, such as the multi-point control of surface temperature
using multiple heaters. It directly controls the average temperature of
all points and the temperature difference between points and also
eliminates interference from the control outputs from one point to
another.
The temperature for each point is input and the average temperature for
all points and the gradient temperature (temperature difference) between
each pair of neighboring points is calculated. PID control is performed
using each of these values as a process value. PID manipulated variable
outputs are distributed to prevent the outputs from affecting other PID
control, i.e., to prevent interference. This means that interference from
multiple heaters to other measurement points is reduced and the
temperature of multiple points can be raised and controlled uniformly.

Gradient Temperature
Control Mechanism and Programming Examples
Gradient temperature control finds and
controls the relationship between temperatures for mutually interfering
points, i.e., it finds the average temperature and the gradient
temperatures, which are the temperature differences between points. This
type of control achieves uniform in-plan temperatures.
