Abstract

The invention discloses a method for controlling the rotational speed fluctuation of a compressor, which includes the process of controlling the compressor according to the real-time angular velocity and torque; the process of controlling the compressor according to the real-time angular velocity includes: filtering the shaft error to obtain the angular velocity compensation amount; Compensating the angular velocity compensation amount to the output angular velocity of the phase-locked loop regulator to obtain the compensated angular velocity output; correcting the real-time angular velocity according to the compensated angular velocity output, and controlling the compressor according to the corrected real-time angular velocity; The process of the torque control compressor includes: calculating the difference between the target angular velocity fluctuation and the feedback angular velocity to obtain the first angular velocity difference; filtering the first angular velocity difference to obtain the filtered angular velocity; inputting the filtered angular velocity to The speed loop regulator obtains the output torque; and controls the compressor according to the output torque. By applying the present invention, the effectiveness of suppressing the fluctuation of the rotational speed of the compressor can be improved.

Description

technical field [0001] The invention belongs to the technical field of motor control, specifically relates to a compressor control technology, and more specifically relates to a method for controlling the fluctuation of the rotational speed of a compressor. Background technique [0002] When the compressor used in the air conditioner is running, it is affected by the working principle and control technology of the air conditioner as a load, which makes the load torque of the compressor extremely unstable, easily causing large speed fluctuations, and the compressor is not running smoothly. The unstable operation of the compressor will lead to unstable operation of the entire air conditioner system, causing various adverse effects. Moreover, the unstable operation will also generate relatively large operating noise, which cannot meet the requirements of relevant noise standards and affect the comfort of the air conditioner. This phenomenon is especially serious in single-roto...
