摘要： An apparatus and method for controlling an operation of a reciprocating compressor are disclosed. The apparatus for controlling an operation of a reciprocating compressor includes: a current phase delay value generating unit that calculates a current phase delay value by using a current stroke and a detected current and outputting the calculated current phase delay value; and a reference current generating unit that delays a reference current based on a difference between the current stroke and a stroke reference value according to the current phase delay value. A phase difference between a current and a pulse width modulation (PWM) voltage is estimated, a phase delay value for compensating the estimated phase difference is calculated, and a reference current is delayed as much as the calculated phase delay value for a certain time to thus remove a current distortion phenomenon. Therefore, an operation efficiency of the reciprocating compressor can be enhanced and a precision degree in controlling a top dead center (TDC) can be improved.
