Abstract
A machine control device has a position regulator configured to enable modification of the proportional gain during regulation operations, and has proportional gain setting unit, which sends an instruction to modify the proportional gain to the position regulator based on a position instruction value which is an output of a position instruction unit. In the proportional gain setting unit, when the movement velocity based on the position instruction value from the position instruction unit decreases, that is, when the position instruction value is a value at which the movement distance is short, the proportional gain of the position regulator is set high, and when the movement velocity based on the position instruction value increases, that is, when the position instruction value is a value at which the movement distance is long, the proportional gain is set low.
