Abstract

The invention discloses a method for automatically compensating compressor moment. The method for automatically compensating the compressor moment comprises the following steps of obtaining the target speed and the feedback speed; generating the fluctuation speed according to the target speed and the feedback speed; utilizing a PLL mode to generate a moment compensating angle according to the target speed and the fluctuation speed; obtaining a loading moment reference value and generating a moment compensating amplitude value according to the loading moment reference value; generating a feedforward moment compensating value according to the target speed, the moment compensating angle and the moment compensating amplitude value. By adopting the method for automatically compensating the compressor moment, a loading moment angle and a loading moment amplitude value can be tracked in real time, the debugging time for moment compensation is greatly reduced, and the optimal compensation effect is achieved in a full-working-condition range of a compressor. The invention further discloses a compressor control method, a device for automatically compensating the compressor moment and the compressor provided with the device.

Description

technical field

[0001] The invention relates to the technical field of compressor control, in particular to a compressor torque automatic compensation method, a compressor control method, a compressor torque automatic compensation device and a compressor with the device. Background technique

[0002] In recent years, with the rapid development of frequency conversion control technology and the popularization of the concept of high efficiency and energy saving, frequency conversion air conditioners have been rapidly popularized and applied. The inverter air conditioner achieves the purpose of controlling the room temperature by changing the power supply frequency of the compressor and adjusting the speed of the compressor speed, so that the fluctuation of the room temperature is small, the power consumption is small, and the comfort level is greatly improved.

[0003] At present, all energy-efficient inverter air conditioners on the market use DC inverter compressors, which u...
