Patent ID: 7550941

Claim:
A system for controlling a linear compressor ( 10 ), the linear compressor ( 10 ) comprising: a movable assembly ( 1 ); a motor ( 1 ′) fed by an application voltage (V T ), an electronic switching device ( 52 ); and an electronic circuit ( 51 ) controlling the electronic switching device ( 52 ) to control the application voltage (V T ) applied to the motor ( 1 ′), and the motor ( 1 ′) driving the movable assembly ( 1 ); the system being characterized in that: the electronic circuit ( 51 ) measures an actuation phase (φ C ) of the current circulating in the motor ( 1 ′) and a dynamic phase (φ P ) of the movable assembly ( 1 ) and establishes a relationship between the actuation phase (φ C ) and the dynamic phase (φ P ), determining a measured phase (φ PC ), the electronic circuit ( 51 ) obtains a value of a correction voltage (V F ) from the value of the measured phase (φ PC ), the electronic circuit ( 51 ) obtains a value of a defined voltage (V P ) from a physical position (DP) of the movable assembly ( 1 ), the electronic circuit ( 51 ) actuates on the value of the application voltage (VT) from the sum of the correction voltage (V F ) and the defined voltage (V P ).
