Subject to technical modifications
Control Zones: Control Parameters Xp, Tn, Tv - Correlations and Settings
Xp
P-proportion in % (amplifying factor)
Tn
I-proportion in sec (re-adjusting time)
Tv
D-proportion in sec (rate time)
Adjustment range: 0.1..999.9 %
Example:
100 % = Amplifying Factor 1
50 % = Amplifying Factor 2
200 % = Amplifying Factor 0.5
The smaller Xp, the stronger the
controller reacts.
Adjustment range: 0000..9999 sec
(0000 = no I-proportion)
The I-proportion looks automatically for the
working point of the control section. The
smaller Tn, the stronger the controller reacts.
Adjustment range: 000.0..999.9 sec
(000.0 = no D-proportion)
The D-proportion counteracts against
every change of control deviation.
The larger Tv, the stronger the controller
reacts.
Parameter
Adjustment
Control process/ interference behaviour
Start-up behaviour (setpoint value jump)
Xp
Larger
Higher damping; interferences are stabilized
slowlier
Slower diminution of Y (energy excess);
contingently overshooting
Smaller
Slighter damping; interferences are stabilized
faster; in case of oscillating Y: enlarge Xp
Faster diminution of Y (relative energy)
with oscillating approach to the setpoint
value; enlarge Xp
Tn
Larger
Higher damping; interferences are stabilized
slowlier
Slower diminution of Y (relative energy)
Smaller
Slighter damping; interferences are stabilized
faster; in case of instability: enlarge Xp
Faster diminution of Y (relative energy)
Tv
Larger
Slighter damping; stronger reaction upon
interferences
Earlier “switch-off” before reaching setpoint
value; contingently slow approach to
the setpoint value
Smaller
Higher damping; slighter reaction upon
interferences
Later “switch-off” before reaching setpoint
value; contingently overshooting
