| description | The invention discloses a variable-frequency constant-pressure water supply control method and system, and belongs to the technical field of water supply. The variable-frequency constant-pressure water supply control method comprises the steps that a water pressure set value Ps in a pipeline is obtained; a control output value Psc is obtained according to the water pressure set value Ps in the pipeline; obtaining a water pressure deviation value Pe in the pipeline according to the control output value Psc; obtaining a water pump rotating speed instruction v according to the water pressure deviation value Pe in the pipeline; and obtaining the water pump rotating speed instruction v to complete variable-frequency constant-pressure water supply control. A set value change process control module is introduced, meanwhile, an expert proportional-integral control algorithm is used, the adjustable space of a proportional-integral coefficient is liberated, and under the working condition that the water pressure deviat |
