Abstract

The invention provides an operation control method, an operation control system, a compressor, an air conditioner, and a computer-readable storage medium; the operation control method includes: obtaining parameter information of an electrical load, and collecting a power supply signal The corresponding fundamental wave amplitude; determine the parameter information and the compensation harmonic signal corresponding to the fundamental wave amplitude; determine the duty cycle input to the power factor correction controller according to the compensation harmonic signal. The technical solution provided by the present invention is applied, and the compensation harmonic signal injected into the bus is determined according to the parameter information of the electrical load in the circuit and the amplitude of the fundamental wave of the power supply signal, and then the electrical load is compensated by the compensation harmonic signal so that In the bus capacitor current, the frequency is that the amplitude of the component of the compressor operating mechanical frequency is reduced, thereby alleviating the current fluctuation of the bus capacitor, reducing the heating of the bus capacitor, and increasing the service life of the bus capacitor.

Description

technical field [0001] The present invention relates to the technical field of circuit control, in particular to an operation control method, an operation control system, a compressor, an air conditioner and a computer-readable storage medium. Background technique [0002] Generally speaking, single-rotor compressors are widely used in household air conditioners. During the rotation of the rotor, the load of this compressor is extremely unbalanced when the rotor rotates to different positions, causing the compressor speed to fluctuate greatly within a mechanical cycle. , forming severe vibration, in order to reduce vibration, the general method is torque compensation, that is, according to the speed fluctuation, a feed-forward compensation amount is superimposed on the torque current component controlled by the compressor. [0003] However, this torque compensation method will superimpose a fluctuation with the same frequency as the compressor operating mechanical frequency ...
