Abstract: A linear compressor according to the present disclosure may include a piston reciprocating within a cylinder, a motor providing a driving force for the motion of the piston, a sensing unit configured to sense a motor voltage and a motor current associated with the motor, a discharge portion provided at one end of the cylinder to regulate the discharge of refrigerant compressed in the cylinder, a control unit configured to compute at least one control parameter associated with the motion of the piston using at least one of the motor voltage and the motor current sensed by the sensing unit, and a deep learning operation unit configured to receive the control parameter, and output a compensation value associated with an absolute position of the piston using artificial neural network technology.
