ABSTRACT:
In current servo amplification/control apparatus and method for a reversible DC motor applicable to a vehicular four-wheel steering system, a motor current detection circuit and a motor current feedback circuit are eliminated and a motor counter-electromotive force is estimated using a dynamic characteristic of the motor, a positioning currenu, and an angular displacement information of the motor, and the motor power supply voltage directly measured is corrected using the estimated counter- electromotive force. Thus, a positioning response of the motor is derived which is approximately coincident with a design target even when the motor is rotated at a high speed.
