Beschreibung
Zusammenfassung:	A method for ascertaining volume flow or pressure for controlling a ventilator, operated by an EC motor, of a specific ventilation device to a specific operating point in order to achieve and maintain a specified nominal volume flow strength or nominal pressure of the ventilation device without use of a pressure or volume flow sensor. The volume flow is ascertained by an artificial neuronal network on the basis of a sequential learning method with a number of learning steps. A linking of n artificial neurons in one or more layers is provided. At least one entry layer Pi is provided in order to process a number of I input parameters, that have a direct or indirect influence on the volume flow in the ventilation device.
