  • Patent number: 9444377
    Abstract: A motor drive control device uses a rotor position sensorless control scheme to drive a motor. The motor drive control device includes a rotational speed deriving component, a startup component and a changing component. The rotational speed deriving component derives rotational speed of the motor just before startup of the motor. The startup component starts up the motor by outputting to the motor a drive signal based on at least one of a direct-current excitation scheme that fixes the rotor position in a predetermined position by performing direct-current energization, and a forced drive scheme that accelerates the motor to a predetermined rotational speed by performing forced energization that applies a predetermined voltage and frequency. The changing component changes the drive signal based on at least one of the direct-current excitation scheme and the forced drive scheme in accordance with the rotational speed of the motor derived.

  • Patent number: 9413277
    Abstract: An actuator control device includes an upper-level control unit that sets an upper-level target value of a predetermined control factor relating to driving an actuator, a lower level control unit, and an intermediate control unit. The lower-level control unit has a command input element that receives an input of the upper-level target value and outputs a lower-level target value of the predetermined control factor, an actuator control element that receives an input of the lower-level target value and controls the actuator, and a tracking element that causes an actual value of the predetermined control factor in the actuator to track the lower-level target value. The intermediate control unit causes the actual value of the predetermined control factor in the actuator to track the upper-level target value. The upper-level target value is inputted into the command input element of the lower-level control unit via the intermediate control unit.
