The control method comprises the steps that the operation frequency of the compressor is obtained; determining a compensation current value of harmonic suppression of the compressor according to the operation frequency; determining a feedforward compensation voltage value according to the compensation current value; and compensating the compressor according to the feedforward compensation voltage value. The control method of the compressor comprises the steps that the operation frequency of the compressor is obtained, the compensation current value of harmonic suppression of the compressor is determined according to the operation frequency of the compressor, the feedforward compensation voltage value is determined according to the compensation current value, and the feedforward compensation voltage value is used for compensating the compressor, so that the noise of the compressor is reduced; moreover, the feedforward voltage compensation strategy adopted by the invention can realize high response speed and high robustness, and greatly optimize the performance of the compressor noiseharmonic suppression system.
Description
technical field [0001] The present invention relates to the field of compressors, in particular to a compressor control method, a compressor control device, a refrigeration device and a readable storage medium. Background technique [0002] In related technologies, the basic working principle of the rotary single-rotor compressor is to drive the rolling piston to rotate through the eccentric crankshaft. When the cylinder is compressed, the gas pressure inside the compression chamber changes periodically, resulting in Periodically changing torque pulsation is generated between the rotating crankshaft, which is the basic cause of torsional vibration of the compressor. [0003] However, the torsional vibration of the compressor causes the compressor to work with relatively high noise, which affects the sense of hearing. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. [0005] To this en...
