Abstract

A motor control device. When the motor control device executes pressure control of which a minor loop is speed control or position control, the pressure control is executed in a manner that pressurization or depressurization is performed while a control parameter of the speed control is fixed; a control parameter of the pressure control is gradually increased; an oscillation amount is successively detected and stored. If the oscillation amount exceeds an acceptable value, on the basis of the control parameter of the pressure control and the oscillation amount stored during adjustment, the control parameter of the pressure control is adjusted such that the oscillation amount is equal to or less than the acceptable value.
