Multiphase machines have been recognized in the last few years like an attractive alternative to conventional three-phase ones. This is due to their usefulness in a niche of applications where the reduction in the total power per phase and, mainly, the high overall system reliability and the ability of using the multiphase machine in faulty conditions are required. Electric vehicle and railway traction, all-electric ships, more-electric aircraft or wind power generation systems are examples of up-to-date real applications using multiphase machines, most of them taking advantage of the ability of continuing the operation in faulty conditions. Between the available multiphase machines, symmetrical five-phase induction machines are probably one of the most frequently considered multiphase machines in recent research. However, other multiphase machines have also been used in the last few years due to the development of more powerful microprocessors. This chapter analyzes the behavior of generic n-phase machines (being n any odd number higher than 3) in faulty operation (considering the most common faulty operation, id est the open-phase fault). The obtained results will be then particularized to the 5-phase case, where some simulation and experimental results will be presented to show the behavior of the entire system in healthy and faulty conditions. The chapter will be organized as follows: First, the different faults in a multiphase machine are analyzed. Fault conditions are detailed and explained, and the interest of a multiphase machine in the management of faults is stated. The effect of the open-phase fault operation in the machine model is then studied. A generic n-phase machine is considered, being n any odd number greater than three. The analysis is afterwards particularized to the 5-phase machine, where the open-phase fault condition is managed using different control methods and the obtained results are compared. Finally, the conclusions are presented in the last section of the chapter.

With the growing interest in electrical machines in recent times, the multiphase machine field has developed into a fascinating research area. Their intrinsic features (power splitting, better fault tolerance, or lower torque ripple) make them an appealing competitor to conventional three-phase machines. Multiphase electric drives have been recently used in applications where fault tolerance and continuous operation of the drive are required. However, the difficulties in extending the three-phase conventional current regulation and control structure to multiphase systems still limit their broad applicability in industry solutions. The main objective of this book is to illustrate new advances, developments, and applications in the field of multiphase machines and drives, while exposing these advances, developments, and applications to the scientific community and industry.

Although three-phase electric machines play a great role in almost all industrial applications, they still have limitations to cover high power requirements needed for traction, propulsion and other high power applications. Nowadays, multiphase electric machines with high output power can solve this problem. A multiphase machine does not only provide higher torque per unit volume, but it also provides higher degrees of reliability due to fault-tolerant capability provided by the additional degrees of freedom. This is a crucial issue for safety-critical applications, e.g., electric ship propulsion, air crafts and aerospace applications. This work presents in details a seven-phase induction motor drive based on indirect field oriented control technique with fault-tolerant controller, which allows the motor to ride-through the fault period caused by a phase loss. Using MATLAB simulation, the problem of "phase disconnection" is addressed and two fault-tolerant control strategies are proposed to compensate its effect.

AC motors play a major role in modern industrial applications. Squirrel-cage induction motors (SCIMs) are probably the most frequently used when compared to other AC motors because of their low cost, ruggedness, and low maintenance. The material presented in this book is organized into four sections, covering the applications and structural properties of induction motors (IMs), fault detection and diagnostics, control strategies, and the more recently developed topology based on the multiphase (more than three phases) induction motors. This material should be of specific interest to engineers and researchers who are engaged in the modeling, design, and implementation of control algorithms applied to induction motors and, more generally, to readers broadly interested in nonlinear control, health condition monitoring, and fault diagnosis.

In recent years, electric power conversion systems have drawn a lot of attentions due to rapidly growing interests in transportation electrification and distributed energy system (DER). High-performance power electronics, batteries, and electric machines are the key enabling technologies for accelerating and fostering this trends, and significant efforts have been devoted to developing more efficient, reliable, and cost-effective power conversion systems. This thesis aims to shed light on reliability of motor drive systems for safety-critical applications such as hybrid electric/electric vehicles, off-road vehicles, electrified aircrafts, and ships. A novel fault-tolerant motor drive topology with a new vector control technique is proposed to achieve extremely high-level of reliability and performance. The proposed fault-tolerant motor drive consists of n number of two-phase inverter modules and 2n-phase electric machine (n = 1, 2, or 3). This configuration can also be extended to 6n-phase motor drive topology with 3n number of inverter modules. Each inverter module with the associated two-phase motor winding can produce a constant instantaneous output power and torque using the proposed vector control technique. When n is equal or higher than 2, the proposed fault-tolerant motor drive starts exhibiting both parallel and phase redundancies, which are the key enabling elements of the fault-tolerant operation in multiple open- and short-circuit fault conditions. The design and operation of the proposed fault-tolerant motor drive have been validated analytically, and investigated by extensive simulations (circuit, control, and motor design), followed by experimental verification. The proposed fault-tolerant motor drive topology can be designed in several different configurations depending on the number of inverter modules and phases, attention in this thesis has been limited to three two-phase inverters with a balanced six-phase permanent magnet (PM) motor (n = 3). It has been analytically and experimentally verified that the proposed fault-tolerant motor drive (n = 3) can tolerate up to four-phase open-circuit faults and two-phase short-circuit faults. Several new open- and short-circuit fault compensation strategies have been proposed and investigated in detail. The required overrating factors of the inverter modules and the electric machine for achieving rated output torque in post-fault operation are also studied for optimal and cost-effective fault-tolerant motor drive design.

Unmanned aerial vehicles (UAVs) are being increasingly used in different applications in both military and civilian domains. These applications include surveillance, reconnaissance, remote sensing, target acquisition, border patrol, infrastructure monitoring, aerial imaging, industrial inspection, and emergency medical aid. Vehicles that can be considered autonomous must be able to make decisions and react to events without direct intervention by humans. Although some UAVs are able to perform increasingly complex autonomous manoeuvres, most UAVs are not fully autonomous; instead, they are mostly operated remotely by humans. To make UAVs fully autonomous, many technological and algorithmic developments are still required. For instance, UAVs will need to improve their sensing of obstacles and subsequent avoidance. This becomes particularly important as autonomous UAVs start to operate in civilian airspaces that are occupied by other aircraft. The aim of this volume is to bring together the work of leading researchers and practitioners in the field of unmanned aerial vehicles with a common interest in their autonomy. The contributions that are part of this volume present key challenges associated with the autonomous control of unmanned aerial vehicles, and propose solution methodologies to address such challenges, analyse the proposed methodologies, and evaluate their performance.

Power electronics technology is still an emerging technology, and it has found its way into many applications, from renewable energy generation (i.e., wind power and solar power) to electrical vehicles (EVs), biomedical devices, and small appliances, such as laptop chargers. In the near future, electrical energy will be provided and handled by power electronics and consumed through power electronics; this not only will intensify the role of power electronics technology in power conversion processes, but also implies that power systems are undergoing a paradigm shift, from centralized distribution to distributed generation. Today, more than 1000 GW of renewable energy generation sources (photovoltaic (PV) and wind) have been installed, all of which are handled by power electronics technology. The main aim of this book is to highlight and address recent breakthroughs in the range of emerging applications in power electronics and in harmonic and electromagnetic interference (EMI) issues at device and system levels as discussed in ‎robust and reliable power electronics technologies, including fault prognosis and diagnosis technique stability of grid-connected converters and ‎smart control of power electronics in devices, microgrids, and at system levels.
