Problems solved by technology
[0014] However, according to Korean Laid-Open Patent No. 10-2010-0096536, for detecting the position of the piston or controlling the movement of the piston, the collision between the piston and the discharge part must be accompanied, and therefore, there is a problem that the piston and the discharge part are damaged due to the collision. question
In addition, there is also a disadvantage that the accuracy of control decreases due to the collision between the piston and the discharge part.

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 configuredto 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; anda 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.
Description
technical field [0001] This specification relates to a linear compressor and a control method thereof, more specifically, to a linear compressor capable of controlling the movement of a piston without adding additional sensors and a control method of the linear compressor. Background technique [0002] In general, a compressor is a device that converts mechanical energy into compression energy of a compressible fluid, and is used as a part of a refrigerating device such as a refrigerator or an air conditioner or the like. [0003] Compressors are broadly classified into reciprocating compressors, rotary compressors, and scroll compressors. The reciprocating compressor forms a compression space between the piston and the cylinder to inhale or discharge the working gas, so that the piston performs linear reciprocating motion inside the cylinder and compresses the refrigerant. The rotary compressor forms a compression space between the eccentrically rotating roller (Roller) an...
