Abstract
The technique of vector space decomposition control of voltage source inverter fed dual three-phase induction machines is presented in this paper. By vector space decomposition, the analytical modeling and cont rol of the machine are accomplished in three two dimensional orthogona l subspaces and the dynamics of the electromechanical energy conversio n related and the nonelectromechanical energy conversion related machi ne variables are thereby totally decoupled. A space vector PWM techniq ue is also developed based on the vector space decomposition to limit the 5th, 7th, 17th, 19th,... harmonic currents which in such a system would be otherwise difficult to control. The techniques developed in t his paper can be generalized for the control of an induction machine w ith an arbitrary number of phases.
