Resonance suppression with low-pass filter
When the value of P2-25 is increased from 0, BW becomes smaller. Although it solves
the problem of resonance frequency, the response bandwidth and phase margin is
reduced. Also, the system becomes unstable.
If users know the resonance frequency, notch filter (parameter P2-23 and P2-24) can
directly eliminate the resonance. In this case, notch filter will be more helpful than
low-pass filter. However, if the resonance frequency drifts because of time or other
factors, notch filter will not do.
