Zusammenfassung:	A control system for an electric motor (106) configured to drive a fluid-moving apparatus. The control system includes a drive circuit (120) and a processor (114, 201) coupled in communication with the drive circuit (120). The processor (114, 201) is configured to control the drive circuit (120) to operate the electric motor (106) at a plurality of control values of a control parameter and determine, for each of the plurality of control values, a fluid-flow value and a feedback value, the feedback value corresponding to a feedback parameter, compute a mathematical relationship between fluid-flow rate and one of the control parameter or the feedback parameter, receive a fluid-flow rate demand value, compute an operating setpoint for the control parameter based on the fluid-flow rate demand value and the computed mathematical relationship, and control the drive circuit (120) to operate the electric motor (106) at the operating setpoint.
