PURPOSE:To eliminate the need for a current regulator and a current detector by using output obtained by adding and subtracting each mimic value of motor currents arithmetically operated from the output of a speed regulator and the speed of revolution and back electromotive voltage to and from the output of the speed regulator as the control output of the motor currents. CONSTITUTION:The speed regulator 1 outputs the command value Ea of armature voltage corresponding to deviation between the command value n* of the speed of revolution and the actual value n of the speed of revolution outputted from a tacho-generator 6. A condition observer 8 inputs the command value Ea of the armature voltage and the actual value n of the speed of revolution, and outputs the mimic value ia of the armature currents, the mimic value Ea of the back electromotive voltage and torque mimic value tauL. Deviation EA among the command value Ea of the armature voltage, the mimic value ia of the armature currents, the mimic value Ea of the back electromotive voltage and the torque mimic value tauL is given to a thyristor converter 4 through a pulse generator 3. |
