6.6.7 FILTER ADJUSTMENT
In all mechanical systems there are resonances that can be classified as high, medium or low frequency,
depending on where they are within the bandwidth of the control loop.
To eliminate these resonances, two types of filters are usually used, damping filters for low frequency
alterations and notch filter for high frequency ones.
Low frequency – Vibration Suppression
If the mechanical load end is long and heavy, vibration may easily occur on this part during fast ramps, affecting
the settling time. Such vibration is called low frequency resonance as its frequency is generally within 100 Hz
