Powerful functions for feedback control are provided with a great number of PC elements and
functional units. Examples of applications are:
•
Basic PID control
•
Cascade-coupled controllers
•
Ratio control
•
Manual control from central/local operator’s workplace
•
Controlling final elements with two- or three-position action
•
Override control
•
Batch control
•
Split range
•
Gain scheduling or other adaptation strategies
•
User-defined control strategies combining the range of available algorithms P, PI, PDP,
PIP, DER, INT, FILT-1P/2P, P-DEADB and RAMP.
The built-in features in one of the complex loop controllers, the functional unit PIDCONA, are:
–
Several control modes with built-in priority scheduling
–
Automatic tracking for bumpless control mode changeover
–
Cascade inputs
–
Differentiation, either of the measured value or the control deviation
–
Parameter scheduling
–
Forcing control of the output signal
–
Limitation of set-point and output with respect to amplitude and rate of change
–
Limit supervision with event and alarm handling
–
Powerful operator interface.
–
Self-tuning and adaptive PID algorithm.
It is easy to combine such a loop controller with supplementary functions, for example
interlocking, start-up and shut-down sequences, calculations, process optimization and so on.

The function FUZZYCON allows the user to specify the control algorithm using fuzzy control,
which is an applied science of fuzzy theory. Moreover, the function supports multi variable
input and multi variable output, that is several controlled variables and manipulated variables
can be handled simultaneously. To the operators, FUZZYCON exposes the same “look and feel”
as other functions, that is PIDCON, with respect to object displays and dialogs. This is also true
for other run time features and most of the engineering tasks.
