A digital computer is used in a time sharing technique to control a plurality of control circuits. The frequency of sampling fs may be low in comparison with the frequency of sampling in conventional direct digital control, and the capacity of the digital computer correspondingly be increased, if each variable in the process is controlled according to an analog control, and the analog reference value in the analog control is derived from a digital reference value which is sequentially corrected in accordance with a correction value which is obtained from the comparison of said digital reference value with a digital value derived from the process.
