Claim 12:
13. The method of claim 12, wherein operating the control loop in the first closed-loop mode comprises:
estimating an angle between the rotor and the stator of the PMSM and using the estimated angle as the transformation angle of the Park transformation;
computing a third error signal by subtracting the first current component from the first reference current value having the first constant value;
computing a fourth error signal by subtracting the second current component from the second reference current value having the second constant value; and
generating the driving voltages for the windings of the stator of the PMSM based on the third error signal and the fourth error signal.
