Variable-frequency constant-pressure water supply control method and system
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 deviation is small, a large proportional-integral coefficient can be set to improve the water pressure adjusting speed, and overshoot cannot be caused.
本发明公开了一种变频恒压供水控制方法及系统，属于供水技术领域。其中，一种变频恒压供水控制方法，包括获取管道内的水压设定值Ps；根据管道内的水压设定值Ps得到控制输出值Psc；根据所述控制输出值Psc得到管道内的水压偏差值Pe；根据所述管道内的水压偏差值Pe得到水泵转速指令v；获取所述水泵转速指令v完成变频恒压供水控制。本发明引入设定值变化过程控制模块同时使用专家比例积分控制算法，解放了比例积分系数的可调空间，在水压偏差比较小的工况下，可以设置一个比较大的比例积分系数提高水压调节速度且不会引起超调。
