METHOD AND DEVICE FOR AUTOMATICALLY COMPENSATING FOR MOMENT OF COMPRESSOR, COMPRESSOR, AND CONTROL METHOD FOR SAME

摘要

Disclosed is a method for automatically compensating for moment of a compressor, comprising the steps of: acquiring a target speed and a feedback speed; generating a fluctuation speed from the target speed and the feedback speed; generating a moment compensation angle from the target speed and the fluctuation speed by means of a phase-locked loop; acquiring a load moment reference value, and generating a moment compensation amplitude value from the load moment reference value; and generating a feed-forward moment compensation value from the target speed, the moment compensation angle and the moment compensation amplitude value. The method for automatically compensating moment of a compressor can track in real time a load moment angle and the load moment amplitude value, so as to greatly reduce the debugging time of moment compensation and achieve the optimal compensation effect in all working conditions of the compressor. Also disclosed are a control method for a compressor, a device for automatically compensating moment of a compressor, and a compressor comprising the device.
