Abstract
A pumping apparatus includes a pump chamber, a piston, a motor, and a controller. The controller determines an imaginary terminal point by referring to a dispense command, theoretical information, and a current position of the piston. The controller corrects the imaginary terminal point to a target position by referring to a correction graph. The controller outputs a drive command to the motor for moving the piston from a start position to the target position.
