• If you observe a noisy sensor feedback signal, reduce the FL filter
setting to about 100 (providing your test does not reach 100 Hz).
If additional adjustment is needed, reduce the setting by 5 - 10 Hz
at a time.
Stabilization Filter Use this feature to define the characteristics of the stabilization filter,
which works with the S Gain to integrate a second signal in the control
mode as a stabilizing factor. Some systems with a higher actuator
frequency may benefit from changing the filter setting for the
stabilization signal.
Stabilization filters are only available for control modes equipped with
stabilization resources and include:
• A 1 Hz High-pass filter that attenuates signals below 1 Hz.
• A Band-pass filter that attenuates signals outside of a user-
definable band.
Stand-Alone Systems To select a Stabilization filter, select, and set up the desired filter type
of 1 Hz High-pass or Band-pass.
Path: Tuning > Manual > Stabilization Filter > Filter Type
–For Band-pass filters, use Filter Min and Filter Max to set
the frequency band.
Note Some systems with a higher actuator frequency may benefit by
selecting the following frequency limits: a low cut-off frequency
(Filter Min) that is approximately the actuator frequency and
a high cut-off frequency (Filter Max) approximately 5-10
times the actuator frequency.
Refer to “Tuning” in Chapter 3, Menus Descriptions of the FlexTest SE
Users Manual for more information about the stabilization filter settings.
Automated Systems See “How to Enable a Tuning Filter” in Chapter 5, Tuning of the Model
793.00 System Software manual for a detailed procedure for changing
the stabilization filter setting.
