COMPLEX RADIO CONTROL SYSTEM
5.5. Vibration analysis and filtering
Vibrations are an unwanted phenomenon in any stabilisation
system, as they affect the measurement with "noise". In the receiver
menu, you can view a graph of the current vibration level. If the
vibrations are high (about half the range of the Y-axis in the graph),
we recommend taking some steps to reduce them:
- stick the receiver with soft double-
sided adhesive tape (included in the
package)
- here you enter the frequency of the digital filter (in Herz units) to
suppress noise of the derivative component of the stabilization
control loop. Recommended value of 20Hz should be modified
with caution.
- use a balanced propeller.
- fix the cables leading to the receiver so
that they cannot move freely in the
model or transmit vibrations
5.5.2 PID Derivative Low-Passfilter
REX Assist receivers have a graphical vibration analyzer and
advanced digital vibration filtering algorithms. In this way, it is
possible to suppress unwanted effects caused by vibrations in the
model. The analyzer graphically displays the intensity of vibrations
at different frequencies, and with the help of two filters you can
subsequently eliminate their negative effects on the functions of
the stabilisation system. Filter settings are in the receiver menu
"Configuration/ Advanced settings" section "Gyroscope
filtering".
