“…This approach is possible in FB VSCs without any modifications. FB VSCs are, in fact, relatively common in drives tolerant to stator SCs: e.g., using multiple H-bridges (which also offer high electrical isolation between phases for dc-link faults or switch SCs) [89,93,95,96,99,130,162,164,165,[210][211][212]223,227,228,233,240,[264][265][266]271] or a single FB VSC [94,128,248,263,267].…”

“…In addition, using vertical conductors within slots can also be helpful for preventing excessive SC current in case of turn faults close to a slot opening, at the expense of higher ac losses [223,227,495]. From Table 10, the most popular multiphase machines for tolerating stator SCs are arguably symmetrical six-phase SPMSMs with single-layer 12-slot 10-pole FSCW [100,101,128,163,165,210,211,231,265]. A lot of research has also been performed recently about a nine-phase three-sector PMaSynRM with overlapping windings [97,98,129,167,224,[235][236][237][238][242][243][244][245]270], although this one has only been employed by a single research group in the literature so far.…”

A Comprehensive Survey on Fault Tolerance in Multiphase AC Drives, Part 1: General Overview Considering Multiple Fault Types

Multiphase drives offer enhanced fault-tolerant capabilities compared with conventional three-phase ones. Their phase redundancy makes them able to continue running in the event of faults (e.g., open/short-circuits) in certain phases. Moreover, their greater number of degrees of freedom permits improving diagnosis and performance, not only under faults affecting individual phases, but also under those affecting the machine/drive as a whole. That is the case of failures in the dc link, resolver/encoder, control unit, cooling system, etc. Accordingly, multiphase drives are becoming remarkable contenders for applications where high reliability is required, such as electric vehicles and standalone/off-shore generation. Actually, the literature on the subject has grown exponentially in recent years. Various review papers have been published, but none of them currently cover the state-of-the-art in a comprehensive and up-to-date fashion. This two-part paper presents an overview concerning fault tolerance in multiphase drives. Hundreds of citations are classified and critically discussed. Although the emphasis is put on fault tolerance, fault detection/diagnosis is also considered to some extent, because of its importance in fault-tolerant drives. The most important recent advances, emerging trends and open challenges are also identified. Part 1 provides a comprehensive survey considering numerous kinds of faults, whereas Part 2 is focused on phase/switch open-circuit failures.

“…Since cost and reliability are key parameters, expensive and vulnerable highresolution encoders or resolvers in these harsh and unfriendly environments are undesirable, as they introduce a single point of failure [21], [22]. Creating redundancy in the mechanical position sensor is also not an option because of its impact on cost and required integration space [23]. Although existing sensorless methods [24]- [28] can be implemented in each of the different controllers in an MMD, the desired performance is not guaranteed within the wide speed and torque range for some mission-critical drives [29].…”

Because a modular motor drive is composed of multiple identical pole drive units and controllers, it can be considered as a multi-agent system. This makes modular motor drives particularly interesting during faults, when the remaining healthy agents assure the continuity of operation. Nevertheless, for some crucial information such as the rotor position, these drives still rely on a single sensor which introduces a single point of failure. In this work, this single high-resolution position sensor is replaced by multiple binary, low-resolution position sensors. A vector tracking observer algorithm, implemented in the different controllers, processes this low-resolution sensor data into a position estimate. Subsequently, these position estimates of the different agents are exchanged with other agents using a distributed averaging algorithm. For this latter approach, it is shown in this work that it improves the position estimation under healthy conditions as well as during agent malfunctions. The concept is demonstrated on a modular axial-flux permanent magnet synchronous machine with fifteen pole drive units, each equipped with a low-resolution position sensor, that are assigned to five agents.

“…Jinquan Xu proposed a new sensorless control based on the robust observer, nonorthogonal phase-locked loop (PLL), and variable phase delay compensation. They performed the method on a faulty six-phase PMSM, and it could guarantee excellent speed control performance even under the postfault condition [9]. Although researchers have noticed that sensorless control methods fail when an open-circuit fault occurs on multi-phase motor and proposed serval solutions, they are complicated and computationally intensive.…”

Dual three-phase permanent magnet synchronous motors (DTPMSM) are used in the steer-by-wire system of electric vehicles that require high reliability. Multiple faults should be considered for the steering system, such as open-circuit faults and speed sensor faults. However, the current speed sensorless control methods of the dual three-phase motor are mainly derived from the promotion of the three-phase motor. They fail when an open-circuit fault occurs, leading to the failure of fault-tolerant control. Researchers have noticed this problem and proposed many methods, but they are very complicated and computationally intensive. This paper proposes one type of improved model reference adaptive system (MRAS). By adding certain fault-related restraints to the output of the adjustable model, speed sensorless control can automatically fit the open-circuit fault and estimate accurately even if an open-circuit fault occurs, which makes sure the whole system continues to operate. Simulation results are presented that contain normal operation, open-circuit fault operation, fault-tolerant control operation, and the whole process from start to fault-tolerant operation. The results show that no matter what period the motor is in, the improved speed sensor can accurately estimate the motor speed and position. The improved model reference adaptive system is significant for improving the reliability of the motor steering system and ensuring the safety of people and property.
