“…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.…”

“…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). For AC/DC converter fault tolerant method, Lee et al proposed a DC-link capacitor estimation when the motor was stopped (Lee et al, 2008).…”

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.

“…HALL SENSOR A Hall sensor is used to sense the presence of magnetic fields and widely used in different ECPSs, such as industrial control systems (ICSs) [19], automotive systems [20], smart grids [21]. In this section, we give a motivational example of a noninvasive sensor-spoofing attack using a Hall sensor of a grid-tied solar inverter in the context of smart grids.…”

Recent decades have observed the proliferation of sensors in embedded and cyber-physical systems (ECPSs). Sensors are an essential part of embedded and CPSs and serve as a bridge between physical quantities and connected systems. The tight coupling between sensors and systems enables many critical applications where decisions are taken by using the information from various sensors at different time-scales. This tight coupling opens the "Pandora's Box" of unknown threats that could come from very unconventional ways. An unconventional attack model could be to noninvasively attack sensors using forged spoofing signals and trigger unwanted behavior in connected systems. This paper introduces this type of new, strong, and unorthodox attack model and elaborates how important this will be in the near future when sensors will pervade our lives. Moreover, this paper presents a motivational example of a sensor-spoofing attack on Hall sensors in the context of smart grids to demonstrate the harmful consequences of this type of attack in ECPSs.

“…The DC-link current second harmonic component monitoring is employed for sensor fault diagnosis [11]. Mehta et al [12] used analysis of the output sensor signals values sequences as binary numbers, the sensor faults can be detected. In healthy conditions, the sequence of three Hall-Effect sensors values (0 for OFF state and 1 for ON state) is expressed as one of the six binary numbers (from 001 to 110).…”

In this paper, a new online technique for Hall Effect sensor fault diagnosis in brushless DC (BLDC) motor is proposed. The proposed technique is based on phase current waveform analysis and does not need any Hall sensor information. The normalized phases current values are analyzed per and post-sensor fault in every cycle. Using a definition of suitable conditions and threshold values for normalized currents values, all sensor fault types (i.e. set to 0 and 1) could be detected and located online effectively. The main contribution of this paper is introducing an online BLDC sensor fault detection and location technique under low-speed operation and transient conditions. Simulation results show the effectiveness of the proposed technique in all of the sensor faults types diagnosis without any sensor output value information. Two different types of BLDC motors are considered for fault diagnosis using the proposed technique. Simulation results during starting and low-speed operations of BLDC motor are well confirmed by the experimental results.
