Abstract

PURPOSE:To keep a constant air flow rate even air flow resistance is changed by comparing a standard impressed voltage calculated correspondingly to an RPM signal and an applied voltage and controlling an apparatus for controlling an air flowing DC motor through the applied voltage. CONSTITUTION:A datum VR determining a controlled volume of a current control element 14 is called as an initial value VRO, and a condition of a mode switch 21 and a change-over resistance 12, applied voltage and RPM are AD- converted and respectively input to read out a control function Gn determined according to both the conditions of mode and the change-over resistance from ROM. Next, the necessary impressed voltage VE is determined according to a real RPM NF to obtain a variation X between the standard voltage VE and the real impressed voltage VE'. This variation X is zero when the air flow resistance is a standard one. When the real air flow resistance is larger than the standard value, the control volume VP of the current control element 14 is increased by a fixed value B and the above described operation is repeated after a fixed waiting time. While, when the resistance is small, it is decreased by a value beta.
