Abstract
A system for controlling a linear compressor, generates freezing force as a piston reciprocates according to rotation of a motor which receives alternating current power through a triac. The system includes a controller which moves up or delays a trigger signal corresponding to an absorption cycle or a compression cycle, such that the center point of the piston reaches a resonant point when a current and a phase difference of the motor deviate from predetermined ranges.
