A control apparatus includes a control unit that controls a first motor and a second motor. The control unit controls a rotation angle of a driven unit using one of the first motor and the second motor based on a direction of disturbance and controls, using the other of the first motor and the second motor, backlash removal from a decelerating unit configured to transmit an output of the first motor or the second motor to the driven unit.
