Control method for compressor and compressor system

A compressor system, comprising:

• a compressor;
• a vibration sensor configured to detect a vibration amplitude of the compressor;
• a frequency converter configured to provide power to the compressor;
• and
• a controller configured to determine whether the vibration amplitude of the compressor is greater than or equal to a predetermined threshold, and to modulate a frequency of the compressor or/and change a switching frequency of a frequency converter if the detected vibration amplitude of the compressor is greater than or equal to the predetermined threshold.

A control method for a compressor, the control method comprising:

• a detection step of detecting a vibration amplitude of the compressor;
• a determination step of determining whether the detected vibration amplitude of the compressor is greater than or equal to a predetermined threshold;
• and
• a speed adjustment step of modulating frequency of the compressor and/or changing a control parameter of a frequency converter if the detected vibration amplitude of the compressor is greater than or equal to the predetermined threshold.
