Abstract
An apparatus and method for controlling a linear compressor and a linear compressor and a refrigerator having the same are provided. The apparatus may include a drive configured to drive the linear compressor based on a control signal, a detector configured to detect a motor current of the linear compressor, an asymmetric current generator configured to generate an asymmetric motor current by applying a current offset to the detected motor current, and a controller configured to generate the control signal based on the asymmetric motor current. The current offset may be changed based on a change in a position of a piston of the linear compressor.
