“…The faulty cases include: one diode opened, one diode short-circuited, and a degradation of the DC-link capacitor. The fault-tolerant control of AC/DC converter for an SPMSM drive system has not been investigated by previous papers (Jlassi et al, 2017;Eickhoff et al, 2018;An et al, 2015;Zeng et al, 2017;Liu and Chang, 2019;Liu et al, 2021;Akin et al, 2008;Vas, 1993;Chai et al, 2019;Liu et al, 1993;Liu and Chang, 2019;Li et al, 2017;Hadef et al, 2010;Mehta et al, 2015). The paper first time proposes to measure the input AC side currents to diagnosis the open circuit or short-circuited for a full-bridge rectifier, and then to execute its faulttolerant control.…”

“…Liu et al used algorithms to improve the dynamic responses when the inverter has one IGBT open circuited or short circuited . In addition, Liu et al also proposed a predictive controller and a sliding-mode estimator to improve the reliability of the SPMSM drive system when one Hall-effect sensor or the encoder is faulty (Liu and Chang, 2019). Several researchers focused on a novel faulttolerant inverter (Li et al, 2017), stator turn fault tolerant method (Hadef et al, 2010), and Hall sensor fault tolerant method (Mehta et al, 2015).…”

Fault tolerant drive systems have played an increasing role for electric vehicles in order to improve reliability, availability, and to reduce maintenance. For safety reason, a fault-tolerant drive system, which includes some redundant devices and a traditional motor drive system, has been developed. This fault-tolerant system executes real-time fault detection, diagnosis, isolation, and control to make the fault-tolerant drive system operate normally even though some faults have happened. In this paper, an AC/DC converter faults, which includes a single-phase full-bridge rectifier diode fault, a three-phase full-bridge rectifier diode fault, and a DC-link capacitor fault are investigated. The fault-tolerant processes include fault detection, diagnosis, isolation, and control to improve the reliability of the drive system and reduce the disturbances during faulty interval. A digital signal processor, manufactured by Texas Instruments, type TMS320F2808, is used as a control center to achieve the fault tolerant processes. Experimental results validate theoretical analysis to demonstrate the correctness and feasibility of the proposed methods. The proposed method can be easily implemented in industrial products due to its simplicity.

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.
