Current setpoint filters

Description
The four current setpoint filters connected in series can be parameterized as follows:
● Low-pass 2nd order (PT2: -40 dB/decade) (type 1)
● General filter 2nd order (type 2)
The phase frequency curve is shown alongside the amplitude log frequency curve. A phase
shift results in a control system delay and should be kept to a minimum.
