Field Orientated Control of 3 Phase AC Motors (PDF 24p):
The principle of vector control of electrical drives is based on the control of both the magnitude and the phase of each phase current and voltage. For
as long as this type of control considers the three phase system as three independent systems the control will remain analog and thus present several drawbacks.
