PURPOSE:To prevent the variation of armature voltage by the variation of field currents generated due to the variation of armature currents by disturbance by using the currents and voltage of an armature circuit as one-way command from a field control system. CONSTITUTION:A field pattern corresponding to the output signals of a pattern generator 1 outputted from a field pattern generator 9 is multiplied by the output of a speed pattern generator 17, compared with the field currents of of a field coil 8 and added to a power amplifier 13. An armature current pattern corresponding to the output signals of the pattern generator 1 outputted from an armature current pattern generator 15 is multiplied by the field currents of, compared with larger signals between the armature currentsIa and the armature voltage VM and added to a power amplifier 6. Accordingly, the DC motor with the field coil singly controlled can stably be controlled. |
