    摘要: A first determining section determines whether a recording medium is conveyed in a first direction. A setting section sets a first current value as a current initially outputted to a DC motor each time the first determining section determines that the recording medium is conveyed in the first direction. A first current outputting section outputs a current at the first current value, and subsequently outputs by steps a current gradually higher than the first current value motor until the first determining section again determines that the recording medium is conveyed in the first direction. A second determining section determines whether the recording medium is conveyed in a second direction opposite the first direction after the first current outputting section outputs a current at the first current value. A first updating section updates the first current value to a second current value higher than the first current value, when the second determining section determines that the recording medium is conveyed in the second direction.

    摘要: A motor driving device, which drives a DC motor, includes a motor driving unit, a status determination unit, and an initial value renewal unit. The motor driving unit repeatedly performs a change-over, wherein the motor driving unit changes an amount of a current inputted into the DC motor to an initial value at a predetermined timing, and then gradually increases the amount of the current from the initial value, in order to slowly move a driving target, driven by rotational force of the DC motor, in a moving direction. The status determination unit determines whether or not the driving target is in a predetermined status. The initial value renewal unit changes the initial value when the status determination unit determines that the driving target is in the predetermined status.

    摘要: A motor control device of the present invention includes a correction input unit, a measurement unit, a first signal processing unit, and a second signal processing unit. The correction input unit corrects a control input signal outputted from a controller, and inputs a corrected control input signal into a motor.

The first signal processing unit inputs a measurement signal representing the physical quantity inputted from the measurement unit into an inverse model 1/G of a transfer function G of a controlled object, and filters an output of the inverse model 1/G through a first low-pass filter. The second signal processing unit obtains a corrected control input signal to be inputted into the motor by the correction input unit, and filters the control input signal through a second low-pass filter.

    摘要: An adaptive control device includes an identifier and a feedforward controller. The identifier estimates an unknown coefficient in a discrete-time transfer function model of a controlled object to identify the discrete-time transfer function model. Estimation is performed based on a manipulated variable supplied to the controlled object and a controlled variable of the controlled object to the given manipulated variable. When estimating each coefficient of the discrete-time transfer function model, the identifier estimates a single unknown coefficient in numerator in non-expanded form of the numerator.
