5.13.2 Low-pass filter – Reduce high-frequency vibrations
Low pass filters:
In particular when you are using
a heavy camera, it can be necessary to dampen
any emerging resonances with a low-pass filter.
As the D factor favours the PID control
resonances in connection with heavy cameras at
high frequencies, a low-pass filter can dampen the
amplification of high frequencies and as such
improve the stability of the system.
However, a disadvantage is a resulting negative
phase delay, which adversely effects the PID
stability.
Therefore, it is somewhat complicated to
configure this filter and its use is not always
justified.
