Abstract: A control system is provided for an electric motor configured to drive a fluid moving apparatus to generate a fluid-flow. The control system includes a drive circuit configured to regulate power supplied to a stator of the motor to turn a rotor and generate the fluid-flow, and a processor that computes a value proportional to at least one of a system resistance or a static pressure for the fluid moving apparatus based on a fixed set point for a first control parameter and a feedback parameter. The processor receives a fluid-flow rate demand and computes an operating set point for a second control parameter based on the fluid-flow rate demand and the value proportional to the system resistance or the static pressure. The processor controls the drive circuit based on the operating set point to supply power to the motor and operate the fluid moving apparatus to generate the fluid-flow.

Abstract: One aspect of the disclosure includes a fluid moving system. The fluid moving system includes a fluid moving apparatus configured to convey a fluid through a housing from an inlet to an outlet. The fluid moving system includes an active cleaning device configured to neutralize or remove at least a portion of an undesired matter from the fluid conveyed through the housing. The fluid moving system includes an electric motor including a rotor coupled to the fluid moving apparatus and configured to turn the fluid moving apparatus upon application of electric power to a stator of the electric motor. The fluid moving system includes a motor controller communicatively coupled to the electric motor and configured to control at least one of a speed output or a torque output thereof.

Abstract: 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.
