Abstract

A motor control device includes a first control unit performing feedback control on a motor with a command value; one or plural second control units performing feedback control on the motor with a limit value; a control switching unit selecting, based on a deviation between the limit value and a measured value, one of the first and the one or plural of second control units as control unit. The first control unit has a first calculation unit calculating a control value, based on a deviation between the command value and a measured value of the motor related to the command value. Each second control unit has a second calculation unit calculating a control value, based on a deviation between the limit value and a measured value of the motor related to the limit value. The first and second calculation units share terms of a calculation expression of the control value.
