6.7.3.1 Low pass filter
The low pass filter in the control system is used to suppress the high-frequency noise or machine
vibration. The Bode plot of low pass filter is given in figure 6.7.3.1.1. Modifying the filter parameters (fr, xi)
will affect the frequency response of various control loop analysis. This is used to simulate the frequency
response of control system plus low pass filter to facilitate the actual adjustment.
(1) fr: The cutoff frequency of filter. The unit is Hz. For general applications, a good effect can be
achieved at the setting of 500 Hz. Other cases can be considered to decrease this value. However,
the control performance will be reduced if the cutoff frequency is too small.
(2) xi: The damping ratio of filter. Its value ranges from 0 to 1.
(3) k1: Low pass filter = 0.
(4) k2: Low pass filter = 0.
