“…DFIG designs with larger 𝐿 𝑘𝑟 may be considered as well, but they translate into higher power ratings for the VSI. Oversizing the converters or adding extra-legs for redundancy [59] provides some fault tolerance but does not tackle the issues of LVRT and cannot be considered an adequate solution on its own.…”

The Doubly Fed Induction Machine has been traditionally adopted in adjustable-speed ac power generation drives in order to take advantage of the reduced rating for the power electronic interface. Aside this well-established application where the DFIG is controlled by a back-to-back converter, recent literature records a growing interest towards un-conventional DFIG drives for dc power generation, combining DFIG high control freedom with simplified power electronic interfaces to achieve an overall cheap and fully-controllable system. Despite several concepts have been demonstrated on small-scale rigs, there is a lack of systematic comparison among different topologies and control solutions. This paper bridges this gap by providing a review of recent topologies, their control, design and performance, and operation issues. As major novelties the paper includes off-spec performance comparison of different torque-ripple mitigation strategies, discussion of sizing requirements for generator and power electronics, fundamental aspects of the behavior under voltage dips, and priorities and challenges for future research on the subject.

Summary This paper addresses the diagnosis of open‐switch fault in pulse‐width modulation (PWM) power converter based on insulated‐gate bipolar transistor (IGBT) used in doubly‐fed induction generator‐direct current (DFIG‐DC) system. The fault diagnosis is carried out by analyzing the rotor currents within healthy and faulty operation conditions. In the new proposed configuration of DFIG connected to DC‐bus, the diode rectifier is employed to connect the stator windings to the DC‐bus and the PWM power converter is employed to connect the rotor windings to the DC‐bus. The main goal of using a PWM power converter is to keep the stator voltage and frequency constant at rated values. In this regard, the various experimental results for open‐circuit faults are obtained by using dSpace DS1104 control board. Some experimental results are obtained, proving the effectiveness of the proposed diagnosis approach such as low detection time and high robustness against false alarms.

“…Consequently, a fault-tolerant control (FTC) has been considered to ensure a good performance even in faulty conditions. [5][6][7] Within this same scope, several work using FTC can be cited. [8][9][10][11][12] The robust sensor fault estimation of the motor current is established based on HN performance index.…”

Electric power steering is an advanced steering system that uses an electric motor to improve steering comfort of the car. As a result, the failures in the electric motor can lead to additional fault modes and cause damage of the electric power steering system performance. Hence, to ensure the stability of this latter, the present paper proposes a new method to reconfigure the fault control. A novelty approach of fast fault estimation based on adaptive observer is also proposed. Moreover, to guarantee optimal and fast control, a fault-tolerant control based on inverse bond graph modeling is designed to construct the behavior of the nominal system. The simulation and the experimental results on a real electric power steering system reveal the importance of the control strategy and show that the proposed approach works as intended.
