The present invention provides a control device for controlling a device using a delta sigma modulation algorithm. Technical problems to be solved by the invention is applied in making changes to the operating control object, can also be a delta sigma modulation appropriate for the operation, to the amount of operation after modulation applied to the control object. The control device of the invention includes a controller for controlling the amount of calculation for the operation object, so that the output of the convergence control object to the target value; and a modulator, used to modulate the amount of operation of a delta sigma modulation algorithm, sigma delta modulation algorithm and delta modulation algorithm, is applied to generate to the control object of the modulation signal. The modulator further generates the modulation signal so that the central value of the amplitude of the modulated signal follows the change in the amount of operation. Thus, even when the amount of operation changes, a modulation signal capable of reflecting the amount of the operation without loss is generated.
