Abstract
A working machine feed axis control device: disposes a velocity feedback loop and forms a cascade coupling on the inner side of a location feedback loop; comprises a velocity gain setting apparatus () which multiplies the output of the velocity feedback look by a first gain (kv), and a location gain setting apparatus () which multiplies the output of the location feedback loop by a second gain (kp); subtracts the output of the velocity gain setting apparatus () and the output of the location gain setting apparatus () from a torque instruction (τ); and outputs the remaining torque instruction (τ) to a subject to be controlled ().
