PURPOSE:To attain the servocontrol with high accuracy with a compact and light-weight servomechanism by using a digital arithmetic circuit which calculates directly the feedback quantity and delivers an action signal. CONSTITUTION:The reference value based on the target value given from the outside of a control system is applied to a multi-processor 11. At the same time, the feedback quantity is also applied to the processor 11 to perform a comparison operation, etc. Then an action signal of a digital electrical signal produced from a parallel PCM signal is delivered to ensure the optimum control based on the result of the above-mentioned comparison operation, etc. This action signal is applied to an analog converting mechanism 12 in the form of an operation quantity. Then the displacement, acceleration, or speed, etc. produced by the control quantity of an analog operation of an object 13 to be driven by the analog machine driving power are detected by an A/D converting mechanism 14 and converted directly into a digital electrical signal of the parallel PCM signal to be applied to the processor 11 in the form of a feedback quantity.
