Disclosed is an apparatus for controlling a driving of a reciprocating compressor and a method thereof, in which a cooling capacity is decreased without a re-expansion loss by controlling a driving of a compressor used in a refrigerator by using a current offset when the cooling capacity of a refrigerator is varied. To this end, in the compressor which controls the cooling capacity by varying an inner stroke according to a stroke reference value set by a user, the apparatus comprises a storage unit for storing a current offset value corresponding to a cooling capacity variable amount; an adding unit for adding the current offset value to a current value applied to the compressor in accordance with that the cooling capacity is varied by a user; a microcomputer for generating a switching control signal corresponding to the current value added from the adding unit; and a power supply unit for controlling a driving of the compressor by applying the added current to the compressor under a dependent state on the switching control signal.
