12.33.3 Current setpoint filter

Possible filter combinations

Filter 1 is configured as a low-pass filter as standard.

Low-pass filters must be dimensioned such that resonance is kept reliably low while the filter

effect on the fundamental frequency range is minimized.

Filter in the case of resonance in the fundamental frequency range

Resonance in the fundamental frequency range can normally be restricted by means of control

Smoothing filters have a negative phase rotation (low-pass generally, bandstop for f < fs, fs

= blocking frequency). This phase rotation can reduce the stability margin of the fundamental

frequency range.

When a filter is used, therefore, the objective must be to obtain the optimum from

desired damping action and

minimum possible filter effects on the fundamental frequency range.
