    DFIM is that it provides variable speed using a small and economic power converter. These machines are controlled by a converter connected at the rotor, where the power is only a small fraction, approximately equal to the slip, of the stator power. This characteristic makes the DFIM especially suitable for applications where the slip is narrowly limited, such as wind turbines

    We have a power supply that goes through a R1 and a variable R2 resistor. We can adjust manually its Vout with a potentiometer. Our goal is to maintain Vref stabilized to a preset manual value SET Vref (with a potentiometer) despite the change of load (R1, R2, R1+R2). At this point you have to understand that Vout is not the Vref. Vout has to be adjusted as much as it has to maintain Vref equal to...
