Method and device for controlling and/or regulating a fluid conveyor for conveying a fluid within a fluid line

摘要

A method for controlling/regulating a fluid conveyer for conveying a fluid within a fluid line is provided. The method includes the steps, receiving information regarding a setpoint flow rate of the fluid within the fluid line, determining an energy consumption of the fluid conveyer during operation within a working range of the fluid conveyer, controlling the fluid conveyer, with regard to a generated flow of the fluid, on the basis of the information regarding the setpoint flow rate of the fluid within the fluid line in such a way that the setpoint flow rate of the fluid is stained and the energy consumption required for this is minimized, wherein it is taken into consideration that the working range of the fluid conveyer is bounded by a non-linear boundary. Also described is a corresponding device.

1. A method executing software instructions stored in a memory for the open-loop controlling of a fluid conveyor for conveying a fluid inside a fluid line, the method comprising:
obtaining information about a desired flow volume of the fluid inside the fluid line; determining an energy consumption of the fluid conveyor during operation within a working range of the fluid conveyor; open-loop controlling of the fluid conveyor with regard to a generated flow of the fluid based on the information about the desired flow volume of the fluid inside the fluid line in such a way that the desired flow volume of the fluid is achieved and the energy consumption which is required for this is minimized, wherein the fact that the working range of the fluid conveyor is restricted by a non-linear limit is taken into consideration during the open-loop controlling, wherein the working range is defined by a set of pairs of a flow volume and a ratio of a pressure at an inlet and at an outlet of the fluid conveyor, wherein the set of pairs is limited by at least one curved characteristic line; and obtaining information about an actual flow volume of the fluid inside the fluid line, wherein the open-loop controlling of the fluid conveyor is also based on the information about the actual flow volume of the fluid at the delivery points inside the fluid line.
