Abstract
An apparatus and a method for controlling a linear compressor, and a linear compressor operable with high power and low noise are provided. The apparatus may include a reference operating frequency determiner that determines a reference operating frequency at which a linear motor is operated, and an actual operating frequency determiner that determines an actual operating frequency as an arbitrary value included in a predetermined numerical value range in a vertical direction around the reference operating frequency. A correction signal may be determined by the actual operating frequency.
