Apparatus and method for controlling operation of linear compressor using pattern recognition

Abstract

An apparatus and a method for controlling operation of a linear compressor uses a pattern recognition for operating a compressor at an optimum efficiency by recognizing a trace in a graph about relation between a current and a displacement as a pattern and sensing variation of the pattern. The apparatus for controlling operation of the linear compressor using a pattern recognition includes a displacement calculating unit calculating a displacement by being inputted the current detected in the current detecting unit and the voltage detected in the voltage detecting unit, a pattern recognition unit being inputted the displacement outputted from the displacement calculating unit and the current outputted from the current detecting unit and detecting a pattern by using a trace corresponding to the displacement and the current, a stroke controlling unit being inputted a pattern from the pattern recognition unit and outputting a switching control signal according to the inputted pattern, and an electric circuit unit being inputted the switching control signal outputted from the stroke controlling unit and outputting a certain voltage to the linear compressor. Accordingly, it is possible to perform a TDC control of a piston considering an error due to non-linearity characteristics, improve an operation efficiency of a linear compressor and have a wide and precise control region.
