Abstract:
In a motor control device, a velocity feed-forward control portion includes a velocity-side acceleration input portion that outputs received high-order command acceleration as a velocity-side acceleration output; a velocity-side velocity input portion that outputs a received high-order command velocity as a velocity-side velocity output; velocity-side boundary-velocity input portions which are prepared so as to respectively correspond to boundary velocities, and to output velocity-side boundary velocity outputs from the velocity-side boundary-velocity input portions corresponding to the high-order command velocity, the boundary velocities being velocities at boundaries of preset adjacent velocity ranges obtained by dividing a limited velocity range; a velocity-side first weight learning portion that changes velocity-side first learning weights in accordance with a velocity deviation, the velocity-side first learning weights respectively corresponding to velocity-side first outputs; and a velocity-side output portion that outputs, as a second tentative command current, a value obtained by summing velocity-side first multiplication values.
