Abstract

The invention discloses a method for controlling the rotation speed fluctuation of an air conditioner compressor, which includes the process of controlling the compressor according to the real-time angular velocity and torque; controlling the compressor according to the real-time angular velocity includes: filtering the shaft error to obtain the angular velocity compensation amount; according to the angular velocity compensation amount Obtaining the compensated angular velocity output; correcting the real-time angular velocity and controlling the compressor according to the compensated angular velocity output; controlling the compressor according to the torque includes: calculating the difference between the target angular velocity fluctuation and the feedback angular velocity to obtain the first angular velocity difference ; Perform filtering processing on the first angular velocity difference to obtain a filtered angular velocity; input the filtered angular velocity to a speed loop regulator to obtain an output torque; obtain a torque compensation amount according to the first angular velocity difference; according to the torque compensation amount and the output torque to obtain a compensated output torque and control the compressor. 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, in particular relates to compressor control technology, and more specifically relates to a method for controlling rotation speed fluctuation of an air conditioner 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 itself as the load, which makes the load torque of the compressor extremely unstable, which is easy to cause large speed fluctuations, and the compressor runs erratically. The unstable operation of the compressor will lead to unstable operation of the entire air conditioning system, resulting in a variety of adverse effects. In addition, the unstable operation will also generate large operating noise, which cannot meet the requirements of relevant noise standards and affect the comfort of the air conditioner. This phenomenon is particularly seri...
