The following figure shows the system open-loop gain with resonance suppression.
When the value of P2.025 is increased from 0, BW becomes smaller. Although it solves the
problem of the resonance frequency, the response bandwidth and phase margin are reduced.
Also, the system becomes unstable.
If you know the resonance frequency, the Notch filter can eliminate the resonance directly. The
frequency range of the notch filter is 50 – 5000 Hz and the suppression strength is 0 – 32 dB. If
the frequency does not meet the Notch filter conditions, then using the low-pass filter to reduce
the resonance is suggested.
