1. control device of electric motor comprises:

  • The position probing link detects motor position, the output motor position signalling;

    The speed arithmetic unit, the motor position signal that obtains according to the position probing link generates the feedback speed signal of motor;

    Positioner comes the output speed instruction according to the difference between position command and the motor position signal;

    Speed control, poor by input speed instruction and feedback speed signal exported torque instruction;

    The torque controlling unit is controlled motor by the torque instruction of input;

    Disturbance observer is by importing new torque instruction and feedback speed signal, output disturbance torque observe value;

    It is characterized in that, further comprise;

    Disturbance observation output controlling unit by input observation perturbing torque, is exported new perturbing torque amount;

    Adder by addition is carried out in input torque instruction and new perturbing torque amount, is exported new torque instruction.
