In a motor control device controlling a motor by a state feedback control, high control accuracy is maintained regardless of fluctuations in a motor load so as to improve control performance of the state feedback control. A control signal (manipulation amount) outputted from a feedback calculator for controlling the motor is compared to a manipulation threshold set to a manipulation threshold setting register so as to determine the magnitude of a load amount of the motor. The feedback calculator includes an observer and performs the state feedback control of the motor. When the load amount is in normal level, a normal load observer matrix set in an observer table is selected to configure a normal load observer. When the load amount is increased, a high load observer matrix is selected to configure a high load observer.
