Abstract

The invention discloses a speed control method 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; obtaining the angular velocity compensation amount according to the angular velocity compensation amount 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; obtain a torque compensation amount according to the torque compensation amount and The output torque obtains the compensated output torque and controls 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 present invention belongs to the field of motor control technology, and in particular, it is to relate to compressor control technology, and more particularly, it is to relate to an air conditioning compressor speed control method. Background technique [0002] The compressor used by the air conditioner is under operation, which is affected as the air conditioner itself as the load, so that the load torque of the compressor is extremely unstable, which is easy to cause a larger speed fluctuation, and the compressor is not smooth. The compressor operation is uncomfortable to cause unstable operation of the entire air conditioning system, causing a variety of adverse effects. And unstable operation also produces larger operating noise, which cannot meet the relevant noise standard requirements, affecting the comfort of the air conditioner. This phenomenon is particularly serious in single rotor compressors. [0003] Although there is also a method of cont...
