  • Motor control apparatus
    Patent number: 9263976
    Abstract: A motor control apparatus includes: duty calculation units that calculate a duty of a PWM signal based on a deviation between a value of a physical quantity of a motor with a command value; and a duty setting unit that performs setting of the duty based on the duty calculated by the duty calculation units. The duty setting unit maintains a present duty until new duty is input from any one of the plurality of duty calculation units, and updates the duty from the present duty to the new duty when the new duty is input from any one of the plurality of duty calculation units. A PWM signal generation unit generates the PWM signal based on the duty set by the duty setting unit and a carrier signal generated by a carrier signal generation unit.
