PROBLEM TO BE SOLVED: To provide a controller for a linear compressor, capable of operating the linear compressor at all times with high efficiency, even in changing a condition of the load of a cooling system. SOLUTION: This controller comprises a detection means 31 for detecting the temperature or pressure of the cooling system, a frequency determining means 32 for determining the power source frequency on the basis of a detection signal, and outputting a determination signal, and a frequency-changing means 33 for changing the power source frequency of a power source on the basis of the determination signal, and the power source frequency is made to coincide with the resonance frequency without affected by the change of the load condition of the cooling system to operate the linear compressor 1 with high frequency at all times.
