“…Although virtual vectors impose zero x-y voltage components over a sampling period, x -y currents with considerable magnitude may continue to circulate in the stator windings due to machine asymmetries, deadtime effects in the power switches of the VSIs or, in the case of PMSMs, the back-EMF harmonics due to the non-sinusoidal shape of PMs [117][118][119]. Since the elimination of these current harmonics requires the application of non-zero x-y voltages, the concept of dual virtual vectors was introduced in Reference [120].…”

Recently, the control of multiphase electric drives has been a hot research topic due to the advantages of multiphase machines, namely the reduced phase ratings, improved fault tolerance and lesser torque harmonics. Finite control set model predictive control (FCS-MPC) is one of the most promising high performance control strategies due to its good dynamic behaviour and flexibility in the definition of control objectives. Although several FCS-MPC strategies have already been proposed for multiphase drives, a comparative study that assembles all these strategies in a single reference is still missing. Hence, this paper aims to provide an overview and a critical comparison of all available FCS-MPC techniques for electric drives based on six-phase machines, focusing mainly on predictive current control (PCC) and predictive torque control (PTC) strategies. The performance of an asymmetrical six-phase permanent magnet synchronous machine is compared side-by-side for a total of thirteen PCC and five PTC strategies, with the aid of simulation and experimental results. Finally, in order to determine the best and the worst performing control strategies, each strategy is evaluated according to distinct features, such as ease of implementation, minimization of current harmonics, tuning requirements, computational burden, among others.

“…Novel contributions to the multiphase drive control in healthy mode of operation are provided in [19,20]. In [19] the non-sinusoidal power supply technique for multiphase drives is investigated, with emphasis on the third current harmonic injection method that is used for air-gap flux density optimization but has a negative effect on yoke flux density and forces wider yoke irons.…”

“…It is also demonstrated that the nonsinusoidal power supply technique is suitable under heavy load conditions, while use of sinusoidal power supply is advantageous for light load situations. A robust current control scheme for dual three-phase (asymmetrical six-phase) electric machines that notably reduces undesired generated harmonics in the stator current is introduced in [20]. The method is based on a disturbance observer and shows nearly complete elimination (>99% reduction) of harmonic components and robustness against uncertainties.…”

“…23 Up to now, various disturbance observer methods have been used in the speed or current control of PMSM drive system. [24][25][26] But the designed observers above are only applicable for the matched uncertainties. Recently, the disturbance observer control methods 27,28 for the mismatched uncertainties have been thoroughly studied.…”

A novel speed control method based on sliding mode control and disturbance observer is studied for permanent magnet synchronous motor drives. Different from the conventional speed and current cascade control structure in the fieldoriented vector control, the new controller adopts the single-loop control structure, in which the speed and quadrate axes current controllers are combined together. First, a multiple-surface sliding mode controller is designed for the speed control system of permanent magnet synchronous motor. Although the sliding mode controller has the strong robustness for the matched disturbance in the system, it still cannot deal with mismatched disturbance effectively, such as external load disturbance and some parameter variations. Thus, the disturbance observer is introduced to estimate the disturbance in the motor, which is designed by combining the proposed sliding mode controller. Finally, the effectiveness is tested under various conditions by both simulation and experiment. The results show that the designed controller has the fast transient response and robustness under different operating conditions.
