Appendix: Using the Advanced Filter
Designer
The Advanced Filter Designer is a tool that enables you to manually design an
advanced filter by editing its parameters and viewing the filter transfer function. You
access the Filter Designer by clicking Advanced Filter Designer in the Tuning Velocity
Loop dialog box (
section 2.8 ) or the Tuning Position Loop / Tuning Dual Loop dialog
box (sections 2.9 and 2.10 ).
If the settings of the current filter are editable, you can modify the values using the
controls in the Filter Designer dialog box in order to achieve an optimal filter.
The filter may consist of one or two components: Second order component and Pole
component in the Filter Designer dialog box. You may enable or disable one or both of
the components by selecting the None option.
For a notch filter, select Notch filter from the Second order component block. The
following is the notch filter block formula:
s 2 + 2 · d · ω · s + ω 2
s 2 + ω · s + ω 2
The user-configurable parameters are:
ƒ
d: the Damping ratio
ƒ ω = 2 π
f: the notch Frequency
(in Hz)
