Method of and apparatus for controlling motor |
摘要 |
A method of controlling operation of a DC motor including the steps of detecting the level of acceleration caused by the rotation of the output shaft of the DC motor; determining the square root of the detected level of acceleration; and supplying the DC motor with a driving voltage which is determined in accordance with the difference between the square root of the acceleration and a voltage command. This method is carried out by an apparatus which includes a power supply for supplying an electric power to the DC motor; a rotary member rotatable in accordance with the rotation of the output shaft of the DC motor; an acceleration sensor provided on the rotary member for detecting the acceleration of acting on the rotary member; a square root circuit for computing the square root of the output from the acceleration sensor; and a differential amplifier circuit for supplying the DC motor with a voltage which is determined in accordance with the difference between the voltage of the power supply and the output voltage of the square root circuit.
