“…1 [10], where the machine has two sets of three-phase windings, one set is designated as ABC, and the other set is XYZ shifted by 30° electrical degrees. Numerous current control strategies have been developed for the dual three-phase drive system [4][5][6][7][11][12][13][14][15][16][17][18]. Two of the most interesting and widely used strategies are the vector space decomposition (VSD) control [11,13,16,17], which treats the machine as a six-phase machine, and the twoindividual current control [4,5,7,12], which treats the machine as two single three-phase machines.…”

--The relationship between the two-individual current control and the vector space decomposition (VSD) control for a dual three-phase permanent magnet synchronous machine (PMSM) is investigated in this paper. It is found that the VSD control is more flexible on controlling the fundamental current in sub-plane and the fifth, seventh current harmonics in z 1 z 2 sub-plane with different PI gains, while the two-individual current control is comparable to the VSD control in having the same PI gains in the and z 1 z 2 subplanes. It is also found that the two-individual current control may have potential instability issues due to the mutual coupling between the two sets of three-phase windings. If the mutual coupling between the two sets is weak to some extent, then the two-individual current control could have the same dynamic performance as the VSD control without the stability issues. Experiments are conducted on a prototype dual three-phase PMSM to validate the theoretical analysis.Index Terms--double d-q synchronous frame current control, double-star motor, dual three-phase, instability, two-individual current control, VSD control.

In this paper an effective direct torque control (DTC) and stator flux control is developed for a quasi six-phase induction motor (QIM) drive with sinusoidally distributed windings. Combining sliding-mode (SM) control and adaptive input-output feedback linearization, a nonlinear controller is designed in the stationary reference frame, which is capable of tracking control of the stator flux and torque independently. The motor controllers are designed in order to track a desired second order linear reference model in spite of motor resistances mismatching. The effectiveness and capability of the proposed method is shown by practical results obtained for a QIM supplied from a voltage source inverter (VSI).

“…If the angle between two of the three phase windings is γ = 60 • , the loss in the 6k ± 1, (k = 1, 3, ...) harmonics is zero and there is no need to improve this loss. Speed control of a six-phase induction machine can be accomplished by many approaches such as FOC [2], [6], [7] and DTC. Direct Torque Control of a six-phase induction machine has been reported in [3], [8]- [10].…”

In this paper, different switching tables proposed for the Direct Torque Controlled (DTC) of a six-phase induction machine are simulated and implemented. A six-phase induction motor has 64 space voltage vectors which result in increased complexity in the selecting of inverters switching. The unsuitable selection of a switching table leads to large harmonics especially at low speed and it also reduces drive efficiency. A six-phase induction machine has large zero sequence harmonic currents of the order 6k ± 1. These harmonic currents are varied in various techniques. Decreasing this loss is essential in a six-phase induction machine. The main purpose of this paper is to improve the ST-DTC of six-phase induction machines to reduce the voltage and current harmonics and the torque pulsation. Selecting a suitable method for minimizing these harmonics is very important.
