PROBLEM TO BE SOLVED: To provide a control device capable of controlling two electric motors by two processor, for suppressing vibrations generated when mobile power between the two electric motors interfere with each other.SOLUTION: A DSP 11a transmits an obtained speed value of a rotation servo motor 3a to a DPS 11b, receives a speed value of a rotation servo motor 3b from the DSP 11b, and calculates correction amount to a torque command to the rotation servo motor 3a on the basis of the speed value difference between the speed value of the rotation servo motor 3a and the speed value of the rotation servo motor 3b. The DSP 11b transmits the obtained speed value of the rotation servo motor 3b, receives the speed value of the rotation servo motor 3a from the DSP 11a, and calculates correction amount to a torque command to the rotation servo motor 3b on the basis of a speed value difference between the speed value of the rotation servo motor 3a and the speed value of the rotation servo motor 3b.
