A study of induction motor current control using the complex number representation
P.M. Dalton, V.J. Gosbell · 2003
A general representation of current controllers using complex number representation is given by means of a consistent block diagram representation of the controller/motor system. The complex number approach allows a consistent representation of control schemes, as is shown by a survey of common current control techniques. It allows insight into the strengths and weaknesses of different algorithms, for example compensation in rotating and stationary reference frames.>
