Abstract
A motor control device includes: a target value acquisition part acquiring a target value of a control parameter of a motor; an operation amount calculation part calculating an operation amount; an output acquisition part acquiring an output of the control parameter; and a deviation calculation part calculating a deviation between the target value and the output. The operation amount calculation part includes: a first calculation part calculating a first value corresponding to the deviation; a second calculation part calculating a second value in a range not exceeding a predetermined upper limit value based on an integrated value of the deviation; and a third calculation part calculating the operation amount in a range not exceeding an operation amount upper limit value based on the first and second values. The predetermined upper limit value is larger than a value obtained by subtracting the first value from the operation amount upper limit value.
