Abstract

PURPOSE:To improve the response characteristic with the operation of a control system as output regulator by digiral computation of an output and a status vriable for the control containing a DC motor and a power amplifier and command values therefore after they are detected. CONSTITUTION:A DC motor 31 is driven with a power amplifier 30. The revolution v of the motor is detected with a detector 42 and a rotor voltage Ei and a rotor current Ia as status variables for the control are detected with detectors 40 and 41 and the outputs of the detectors are separately converted into a digital values with AC converters 43-45. The outputs and a speed commander provided from a data processing section of an NC control are computed with a control circuit 46 to generate a control input u which is inputted into the power amplifier 30 as control value. This enables the operation of a servo motor control system as output regulator thereby eliminating evils in an analog structure. Thus, a digital control system can be obtained with an excellent response characteristic.
