Abstract:
A control device includes angular velocity detecting circuitry, feedback circuitry, torque command calculation circuitry, a limiter, a drive controller, and correction circuitry. The angular velocity detecting circuitry detects an angular velocity of a motor. The feedback circuitry obtains a feedback value from the angular velocity. The torque command calculation circuitry obtains a torque command value according to a superordinate torque command value supplied from a superordinate device and the feedback value. The limiter limits the torque command value obtained by the torque command calculation circuitry so as not to exceed a preset torque upper limit value. The drive controller performs a drive control of the motor according to the limited torque command value. The correction circuitry corrects the superordinate torque command value or the torque command value according to the feedback value and the superordinate torque command value.
