Abstract
The present invention is to determine allocation of filters in such a manner as to satisfy a restriction for the number of filters while realizing suppression of resonance. The present invention provides a control assistance device assisting in setting a plurality of first filters provided in a servo control device controlling a motor, the control assistance device including: a resonance detection unit for detecting a plurality of resonance points in frequency characteristics including input-output gain and input-output phase lag of the servo control device, the frequency characteristics being measured on the basis of an input signal and an output signal having a varying frequency; a filter setting unit for setting a plurality of second filters the number of which is larger than the number of said plurality of filters in order to suppress the plurality of resonance points; and a grouping unit for grouping the plurality of second filters to set the plurality of first filters.
