Add a notch at frequency 359 Hz with damping factor of 0.07. Click the High-
order Filter Design button, choose a notch filter, type its corner frequency and
use the slider to choose the damping factor. The screen is shown in Figure 69.
Click OK to return to the Tuning Velocity Loop screen, and then click Run to
perform a test. The outcome is shown in Figure 70. Note that the resonance
phenomenon disappeared (compare Figure 67 and Figure 70). The improvement
is apparent in Figure 71, which is zoomed to the scale of Figure 68.
