Abstract: Electric propulsion is widely used in ship propulsion systems, and multiphase machines are gaining increasing popularity because of their fault-tolerant ability, high power density, and reduced torque ripple. This study concentrates on the tandem ship propulsion configuration with two 15-phase induction machines (IMs) fixed on the same shaft. Based on fieldoriented control and reconfiguration fault-tolerant control for the single 15-phase IM, the master-slave coordinated control strategy is designed for the ta… Show more

“…In opposition to the standard virtual vectors, the dual virtual vectors only contain x-y voltage components, hence the control of the x -y currents can be performed without disturbing the reference tracking of the d-q current components, which regulate the flux and torque of the machine. The dual virtual vectors are created by the combination of a large and a medium-large vector with the same phase in the x-y subspace and the duty cycles given by (32), resulting in twelve dual virtual vectors with an amplitude of 0.598 • U dc in the x-y subspace (stationary reference frame), as shown in Figure 6.…”

“…In addition to the reduced current or voltage ratings per phase, lower torque harmonics, improved fault-tolerant capabilities and additional degrees of freedom, multiphase machines also offer other advantages over their three-phase counterparts, namely: improved winding factors, reduced harmonic content in the magnetomotive force (MMF), lower rotor losses and lesser harmonics in the dc-link current [1,[24][25][26]. Nowadays, electric drives based on multiphase machines are employed in a wide range of areas, such as aircraft [27,28], electric or hybrid vehicles [29], locomotive traction [30], high-speed elevators [31], ship propulsion [32], spacecraft [33] and wind energy applications [34][35][36].…”

“…Multiphase motors have been widely used in air-craft drives, locomotive traction, electric ship propulsion and high-power industrial applications [1][2]. As the number of phases increases, the required stator current amplitude can be reduced without changing phase voltages and output power [3][4]. Besides, multiphase motors have competitive advantages over three-phase motors such as lower torque pulsations, higher power density, lower dc-link current harmonics and better power distribution among a higher number of phases [5][6].…”

“…Thanks to the aforementioned advantages, multiphase induction machines are becoming attractive in several sectors especially aeronautics [15], naval [16], and automotive industries [17]. With these increasing demands on multiphase induction machines, the design rules and theories, classically developed for the case of three phases, must be reconsidered.…”
