tF
Within a band B in which periodic fault signals occur, these changes at input E (c**.1) are con-
sidered as faults by the filter and filtered with the set time constant tF. Changes in a direction
leading out of the filter band are passed unfiltered to the output A (c**.A) in order to allow fast
signal change in a controlled system for example. If the fault level changes in the meantime, the
band automatically adapts itself to the new level (Figure 1--22).
Because the filter band sets itself automatically and B is therefore not known, the time constant
tF may only be selected so great that the control loop would not oscillate even at a great filter
band for control technical reasons: tF
<
TG (Tg = delay time of the control system). When
using the D part (PD, PID) use of the adaptive non--linear filter is highly recommended because
the input noise amplified by Kp
⋅
vv can be suppressed.
