摘要： The present invention discloses an apparatus and method for controlling a linear compressor which can actively handle load and efficiently perform an operation, by synchronizing an operation frequency with a natural frequency of a movable member varied by the load. The apparatus for controlling the linear compressor includes a counter electromotive force phase detecting unit for detecting a phase of a counter electromotive force from a voltage command value of the linear compressor and an input current, a current phase detecting unit for detecting a phase of the input current, a frequency generating unit for comparing the phase of the counter electromotive force with the phase of the input current, and generating a frequency change value, a control unit for correcting the voltage command value according to the frequency change value, and an inverter unit for receiving a direct current voltage, generating a sine wave voltage according to the corrected voltage command value, and applying the sine wave voltage to the linear compressor.
