PUMP CONTROL SYSTEM AND METHOD FOR CONTROLLING A PUMP WITH AUTOMATIC PUMP MODEL CALIBRATION

The present disclosure relates to a method for controlling a pump, wherein the method comprises the following steps: - running (501) a pump at a set pump speed (ω) based on an operating value model function (P_ω(q)) corresponding to the set pump speed (ω); - determining (503) an actual operating value (P) at the set pump speed (ω); - comparing (505a, 505b) the actual operating value (P) with a maximum (P_max) of the operating value model function (P_ω(q)) and/or a minimum (P_min) of the operating value model function (P_ω(q)); and - automatically updating (507b) the operating value model function (P_ω(q)) to a higher new operating value model function (P_ω,up(q)) if the actual operating value (P) is higher than the maximum (P_max) of the operating value model function (P_ω(q)), and/or automatically updating (507a) the operating value model function (P_ω(q)) to a lower new operating value model function (P_ω,down(q)) if the actual operating value (P) is lower than the minimum (P_min) of the operating value model function (P_ω(q)).
