●
The above low-pass filter frequency characteristics are obtained from theoretical model
calculations and simulations, and there are some differences with the actual characteristics.
Example 2: The
decay in amplitude diminishes as the Q value gradually increases for the cutoff frequency Pn402 =
1256 Hz of the torque command 2nd order filter.

Example 3
: The cut-off frequency of the torque command 1st order low-pass filter is 1256 Hz and the cut-off frequency
of the torque command 2nd order filter is Pn402 = 1256 Hz with Q = 1.0 The filter frequency characteristics are shown
below.
