Abstract
Disclosed are a compressor control method, control apparatus and control system. The method includes: receiving a cylinder switching instruction, and detecting operating parameters of a compressor; determining whether a cylinder switching operation is completed according to the operating parameters of the compressor; and after it is determined that the cylinder switching operation is completed, performing torque compensation.
Claims17
A compressor control method, comprising:
- receiving a cylinder switching instruction and detecting a plurality of operating parameters of a compressor;
- determining whether a cylinder switching operation is completed according to the plurality of operating parameters of the compressor;
- and
- performing torque compensation after determining that the cylinder switching operation is completed,
- wherein detecting the plurality of operating parameters of the compressor comprises:
- detecting a current operating parameter of the compressor when receiving the cylinder switching instruction;
- and
- detecting a real-time operating parameter of the compressor every first preset time interval,
- wherein determining whether the cylinder switching operation is completed according to the plurality of operating parameters of the compressor comprises:
- calculating a ratio of the real-time operating parameter to the current operating parameter;
- comparing the ratio with a cylinder switching threshold, wherein the cylinder switching threshold is a preset value configured to represent that the cylinder switching is completed;
- and
- determining that the cylinder switching operation is completed when the ratio is greater than or equal to the cylinder switching threshold.
