Title:

LINEAR COMPRESSOR, AND APPARATUS AND METHOD FOR CONTROLLING A LINEAR COMPRESSOR

Document Type and Number:

WIPO Patent Application WO/2016/032168

Kind Code:

A1

Abstract:

In accordance with one aspect of the present invention, an apparatus for controlling a linear compressor, includes: a detector that detects an operating state of the linear compressor; a controller that outputs a correction signal for correcting at least an operating frequency of a linear motor based on the operating state; and a drive signal generator that generates a drive signal of the linear motor according to the correction signal, and outputs the generated drive signal to the linear motor, wherein the controller includes: a reference operating frequency determiner that determines a reference operating frequency at which the 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 around the reference operating frequency, wherein the correction signal is determined based the actual operating frequency.
