    摘要: An image forming apparatus includes a conveyance control unit that controls conveyance of a recording unit. The conveyance control unit switches a conveyance direction of the recording unit at return points on both sides of a scanning direction to reciprocate the recording unit, and controls a speed of the recording unit to a target speed until the recording unit reaches a control changeover point from the return point upstream in the conveyance direction. The target speed is set to be symmetrical in a zone in which the recording unit is shifted to a constant speed state from a start point of an image forming area and in a zone in which the recording unit reaches the end point of the image forming area from a deceleration start point.

    摘要: A conveyance device includes a motor, a conveyance unit, a movement detection signal output unit, a storage unit, a time measurement unit, a first updating unit, a standby time setting unit, a second updating unit, a manipulated variable determination unit, and a motor driving unit. The standby time setting unit sets a value larger than a parameter value TX stored in the storage unit as a standby time TW. The second updating unit updates the parameter value TX stored in the storage unit to the standby time TW each time the elapsed time measured by the time measurement unit reaches the standby time TW.

    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.
