METHOD AND APPARATUS FOR PUMP CONTROL USING VARYING EQUIVALENT SYSTEM CHARACTERISTIC, KNOWN AS ADAPTIVE CONTROL CURVE Russian patent published in 2015 - IPC F04D15/00 F04B49/20 

FIELD: physics, computer engineering.

SUBSTANCE: apparatus comprises a processor and memory including a computer program code, configured to respond to signalling containing information about instant pressure and a flow rate of fluid being pumped in a pumping system, and obtain an adaptive control curve based on the instant pressure and flow rate using an adaptive moving average filter. The adaptive moving average filter may be based on controlling system flow relating to the adaptive moving average filter (AMAF), flow rate and differential pressure of the system, respectively.

EFFECT: processor, memory and computer program code are also configured to obtain an optimal control pressure point based on the adaptive control curve with respect to an instant flow rate or a moving average flow rate to obtain the desired pump speed through a PID control.
