CONSTITUTION: A method and an apparatus for reducing vibration of a compressor based on frequency analysis for speed comprises a vibration reduction operating unit(150), a torque command generator(160) corresponding to vibration, a speed controller(170), and a torque controller(190). The vibration reduction operating unit implements frequency analysis aimed at speed values of a compressor for each time. In case of increasing speed ripple of a specific time, torque is controlled to reduce the relevant speed ripple. The torque command generator generates torque commands according to torque adjusted values. The speed controller generates speed commands for operating the compressor. The torque controller implements inverter control for driving a motor by using values in which the torque commands are added to the speed commands.
