Abstract

In a servo controller according to the invention, a position feedback correction unit () calculates a first-axis position feedback signal (pmfb) based on a first-axis position (pm) as a self-axis position, and a second-axis position (pm) as an other-axis position; and a deviation between a model position (pa) and the first-axis position feedback signal (pmfb) is inputted from a subtracter () to a position control unit (), which performs positional control to output a velocity command. A velocity feedback correction unit () calculates a first-axis velocity feedback signal (wmfb) from a first-axis velocity (wm) as the self-axis velocity, and a second-axis velocity (wm) as the other-axis velocity; and the velocity control unit () adds a model velocity (wa) and the velocity command outputted from the position control unit (), and subtracts the first-axis velocity feedback signal (wmfb) therefrom, and outputs a feedback torque command (Tfb) based on the corrected velocity command.
