“…Compared with the hardware fault-tolerant strategy, the reduced-order decoupling and optimal current fault-tolerant strategies can achieve disturbance-free operation without increasing the requirement of hardware resources. For reduced-order decoupling fault-tolerant control, the control structure is reconstructed through the reduced-order decoupling matrix, which usually requires an additional compensation strategy [20,21].…”

Multi-phase motors have attracted increasing attention in fields seeking high reliability, such as electric vehicles, ships, and rail transit, as they exhibit advantages, such as high reliability and fault tolerance. In this study, we consider a 12-phase permanent magnet synchronous motor (PMSM). First, a mathematical model of the 12-phase PMSM in the static coordinate system is established and the model is simplified according to the constraint condition of neutral point isolation. Second, according to the principle of invariant magnetomotive force under normal and fault conditions, two optimal control strategies of winding current, i.e. maximum torque output (MTO) and minimum copper consumption (MCC), are proposed. For a single-phase open-circuit fault, two optimization methods are used to reconstruct the residual phase current, such that the motor can maintain normal torque output and exhibit lower torque ripple under the fault state. Finally, system simulation and experimental research are conducted; the results verify the accuracy and feasibility of the fault-tolerant control strategy of the 12-phase PMSM proposed in this paper.

“…identify the complex conjugate quantities and the scalar product, respectively. The electromagnetic torque, expressed by (16), is the sum of six contributions, where each one can be identified by the corresponding harmonic order in the flux linkage. Two of them are related to the current space vector i¯S 1 , the second pair is related to the third current space vector i¯S 3 , and the remaining pair is related to the fifth current space vector i¯S 5 .…”

“…With reference to m-PMSMs, it is well known that even if one or more phases are opened due to stator failures, the remaining healthy phases allow the motor to operate with a degraded mode [13,14]. Thus, several fault-tolerant control approaches, against stator asymmetries or inverter related faults, have been the target of large research efforts [15][16][17][18], in order to guarantee reliable operating conditions and thus reducing unexpected failures. However, dedicated solutions for stator winding anomalies detection are still under investigation [19][20][21][22][23].…”

“…The variable-speed multi-spool direct drive architecture with a DC distribution bus was investigated in [25], where the minimum reactive power transfer and reduced overall copper losses are obtained, but transient surge currents and the risk of converter failure are inevitable. In addition, the fault-tolerant operation of five-phase PMSM drive was investigated with short-circuit inverter fault, one phase loss, and third-harmonic current injection in [26]- [28], respectively. Furthermore, a novel ten-phase fault-tolerant PMSM with two stators and two rotors on the same shaft was proposed in [29], and a novel speed control scheme of the developed motor was presented by considering the electromagnetic torque ripple in the fault switch process.…”

This paper presents a review of the electrical and electronic technologies investigated in moreelectric aircraft (MEA). In order to change the current situation of low power efficiency, serious pollution, and high operating cost in conventional aircraft, the concept of MEA is proposed. By converting some hydraulic, mechanical, and pneumatic power sources into electrical ones, the overall power efficiency is greatly increased, and more flexible power regulation is achieved. The main components in an MEA power system are electrical machines and power electronics devices. The design and control methods for electrical machines and various topologies and control strategies for power electronic converters have been widely researched. Besides, several studies are carried out regarding energy management strategies that intend to optimize the operation of MEA power distribution systems. Furthermore, it is necessary to investigate the system stability and reliability issues in an MEA, since they are directly related to the safety of passengers. In terms of machine technologies, power electronics techniques, energy management strategies, and the system stability and reliability, a review is carried out for the contributions in the literature to MEA. INDEX TERMS More-electric aircraft, machine technologies, power electronics techniques, energy management strategies, system stability and reliability.
