The controller in the CLM 153:
The CLM 153 contains a multi-faceted PID controller which can be adapted to the
process. It has the following features:
•
Separate configuration of both process sides,
•
Simple adaptation to batch or inline processes,
•
Switching option between constant and range-dependent modulation gain.
Relating to the effect on the gain factor, a difference is made between two standard
implementations:
•
The factor K
R
(X) is the total gain
(see fig. 21. This is implemented in the CLM 153).
•
The gain factor K
P
(X) is the purely proportional gain.
The following diagram shows the schematic structure of the CLM 153 controller.
Because of the simplicity of the diagram, the Laplace transform of subfunctions is given.
