MOTOR CONTROLLING DEVICE

WIPO Patent Application WO/2012/060180

A1

In order to realize as high speed and highly precise control as possible against mechanical systems with many characteristics, a motor controlling device has a filter characteristic in which, a frequency response gain is approximately 1 when a frequency is equal to or less than a filter cutoff frequency, the frequency response gain is lowered with the increase of the frequency between a filter cutoff frequency (ωfL) and a filter upper limit frequency (ωfH) that is larger than the filter cutoff frequency (ωfL), and the frequency response gain is almost constant when the frequency is equal to or more than the filter upper limit frequency (ωfH). The motor controlling device includes a feedback filter that performs calculation to cause the filter characteristic to act on a feedback transmission function. A control constant setting unit sets a speed gain (Kv) and at least one of the filter cutoff frequency (ωfL) and the filter upper limit frequency (ωfH) so that a ratio of the filter upper limit frequency (ωfH) to the filter cutoff frequency (ωfL) becomes small with respect to the increase of the speed gain (Kv).
