“…Hence, fault-tolerant operation and control are important research topics in this area. Although fault tolerance can be achieved via special machine design [2]- [6] and the use of application-specific converter topologies [7]- [10], the majority of studies [11]- [26] focus on the post-fault control methods for n-phase machines driven by an n-leg voltage source converter (VSC), since this is the most common topology in practice. The discussion here follows this common trend, assuming star-connected stator windings.…”

“…However, it requires additional controller for regulating the zero-sequence current. Hence, in the literature, discussion on healthy operation of six-phase machines is usually based on two isolated neutrals, while fault-tolerant control studies are typically based on single neutral connection [12], [13], [20], [27].…”

“…More vector planes in the multiphase motor can be manipulated to optimize air-gap flux distribution and improve the torque density [9][10][11]. Another distinguished advantage is improved reliability and continuous system operation even in the fault condition [12][13]. This characteristic is crucial for all the applications requiring a high degree of reliability, such as Electric Vehicle (EV) or marine.…”

-This paper deals with fault-tolerant control of five-phase induction motor (IM) drives under single-phase open. By exploiting a decoupled model for five-phase IM under fault, the indirect field-oriented control ensures that electromagnetic torque oscillations are reduced by particular magnitude ratio currents. The control techniques are developed by the third harmonic current injection, in order to improve electromagnetic torque density. Furthermore, Proportional Resonant (PR) regulator is adopted to realize excellent current tracking performance in the phase frame,

The electric power propulsion is becoming the important development direction of ship propulsion technology recent years, as it is conducive to the realization of automation, intelligence, reduced noise, enhanced propulsion efficiency, high power density, flexible arrangement, and energy saving. The good fault‐tolerant capacity and robustness of the fault‐tolerant permanent magnet motor (FTPMM) make it a potentially highly effective and economical propulsion motor in the electric power propulsion ship than other alternatives. In this paper, the structure and mathematical model of FTPMM are analyzed and the improved sliding mode observer (SMO) is constructed according to the deviation between the observed currents and actual currents. Combined with model reference adaptive control (MRAC) method and the phase‐lock loop (PLL), the switch function is replaced by the continuous Sigmoid function to reduce the chattering and finally the rotor position estimated accuracy is improved. When the motor winding open‐circuit and short‐circuit fault occur, the current vector fault‐tolerant control strategy is introduced into the improved SMO algorithm, and the rotor position is estimated accurately under faulty conditions. Finally, the proposed improved SMO position estimation algorithm under healthy and faulty conditions is verified in Matlab/Simulink. The FTPMM position sensorless technology would play a critical role in the electric power propulsion ship, and may have a profound impact on the high‐performance advanced ships and green shipping industry as well. © 2022 Institute of Electrical Engineers of Japan.
