width of the trap varies depending on the notch filter Q value.
The smaller the Q of the notch filter, the wider the depression and the wider the width of the filter frequency.
Example
: notch filter center frequency 1500Hz, trap depth D = 0, in the notch filter depth value (D) at different setting
values amplitude attenuation effect graph.
Precautions
●
The above notch filter frequency characteristics are obtained from theoretical model
calculations and simulations, and there are some differences with the actual characteristics.
Notch filter depth
The notch filter depth is the depth of depression (amplitude) that varies depending on the trap depth setting at a certain
defined notch center frequency, depending on the notch filter depth (D).
The smaller the notch filter depth value (D), the deeper the depression, the better the vibration suppression control effect,
but too small will increase the vibration.
Example
: notch filter center trap frequency 1500Hz, notch filter width Q = 0.7, in the notch filter depth value (D) at different
setting values amplitude attenuation effect graph.

Q=0.1
Q=0.5
