Abstract (en)

A method for an automatic torque compensation of a compressor is provided. The method includes: obtaining a target speed and a feedback speed; generating a fluctuation speed according to the target speed and the feedback speed; generating a torque compensation angle according to the target speed and the fluctuation speed in a phase locked loop (PLL) manner; obtaining a load torque reference value and generating a torque compensation amplitude according to the load torque reference value; and generating a feedforward torque compensation value according to the target speed, the torque compensation angle and the torque compensation amplitude. A method for controlling a compressor, an apparatus for an automatic torque compensation of a compressor and a compressor including the apparatus are also provided.
