As a new type of compressor，linear compressor has the advantages of high efficiency，small volume，low noise and little vibration. However，in order to give full play to its advantages of high efficiency，it is necessary to control the driving frequency to track its mechanical resonance frequency. According to this characteristic，a frequency tracking control algorithm of linear oscillation motor based on second-order generalized integrator （SOGI） and double correlation phase detection algorithm was proposed. Compared with the frequency tracking control algorithm based on the average value of stroke-current product （ASCP），the control algorithm has the advantages of fast dynamic response and stable operation under variable working conditions，enhances the suppression effect of external interference and improves the stability of the control system. Simulation and experiments show that the proposed control algorithm can quickly track the natural frequency of the motor，which verifies the rationality and effectiveness of the theory.
