PROBLEM TO BE SOLVED: To remove the influence by the induced voltage constant of a direct- current motor from the entire control system. SOLUTION: The current feedback controller 1 contains a filter 5 that filters control signals to a motor M in accordance with a specified transfer function; current detecting resistors 7, 8 that detect current passed through the motor M; and a differential amplifier 9 that converts the detected current into voltage and returns it to the stage precedent to the filter by negative feedback. For the transfer function for the filter 5, one in such a relation that the induced voltage constant of the motor M contained in the entire transfer functions related to the control of the motor M is deleted, is used. |
