Abstract: There is provided control system including: movement mechanism configured so that the movement mechanism is driven by motor; detector configured to detect position and speed of the movable member; and controller. The controller is configured to: control the motor so that the movement mechanism reciprocatively moves the movable member; and in a course to move the movable member to a returning point, control the movement of the movable member by controlling the motor based on the speed of the movable member so that the movable member is moved at a constant speed until a deceleration start point of time, and control the movement of the movable member by controlling the motor based on the position of the movable member so that the movable member is decelerated from the deceleration start point of time and stops at the returning point in accordance with a target position locus.

Abstract: There is provided a motor driving system in which an encoder sensor is configured to move with a driven object with respect to an encoder scale and output an encoder signal. A controller is configured to control a motor based on the encoder signal, thereby controlling movement of the driven object. The controller estimates an obstructing area. In the obstructing area, the encoder sensor reads a part of the encoder scale where an obstacle is adhered. The controller calculates a control error of the motor in the obstructing area based on the encoder signal output after the encoder sensor passes through the obstructing area, and determines a compensation amount of a controlling input value input during a period while the encoder sensor passes through the obstructing area.
