Abstract

PURPOSE:To improve the proportional accuracy of a DC motor by correcting the speed reference signal with a voltage drop amont compensating signal of a armature circuit and a compensating signal proportional to the product of the armature current and the speed reference. CONSTITUTION:A speed reference signal 3a is inputted through a voltage regulating resistor Rb and a resistor R3 to a multiplier 40, and is multiplied by an armature current signal 3b through a resistor R4. The output of the multiplier 40 becomes a signal 3d through a resistor R5. The signal 3d is added to a signal 3e obtained by the armature current signal 3b and a resistor Ra, thereby correcting the signal 3a to obtain a reference signal. An arithmetic unit 30 compares and calculates a voltage feedback signal 3c with the reference signal and produces the difference. In this manner, the proportional accuracy can be improved and the stable operation can be performed.
