MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/053212
Kind Code:
A1
Abstract:
A motor control device (11) controls a motor (11) of a machine device (13). The motor control device (11) comprises: a command value calculation unit (31) for calculating a command value (I*) for controlling a motor (12); and a disturbance observer unit (33) for estimating, on the basis of the command value (I*) and the rotation information (ωm) of the motor (12), a disturbance (TId) applied to the machine device (13) and correcting the command value (I*) on the basis of the estimated disturbance (TId). The disturbance observer unit (33) has parameters (L1, β) to be adjusted for compensating the effect of the disturbance (TId) having a specific frequency to be suppressed. The parameters (L1, β) are adjusted so that a disturbance (TIast) applied to the machine device (13) after the effect of the disturbance (TId) is compensated has frequency characteristics corresponding to the anti-resonance characteristics of the machine device (13).
