The More/All Electric Aircrafts are the important trends in modern aerospace for reducing the overall aircraft weight, operation cost and environmental impact. Advanced electrical machine systems are the basement of More/All Electric Aircraft, which are employed to generate electric power and replace existing hydraulic, pneumatic, and mechanical actuators. The rapid development of More/All Electric Aircraft poses new challenges in the design and control of aircraft electrical machine systems. The aim of the proposed special session is to collect and disseminate the latest research and advanced technologies in the field of electrical machines and application for the More/All Electric Aircraft.
Topics of interest include, but not limited to:
• Design and analysis of aircraft electrical machines
• Modeling and simulation of aircraft electrical machines
• Control strategies for aircraft electrical machines
• Power electronics drive for aircraft electrical machines
• Aircraft integrated starter/generator
• Aircraft generators
• Electrical machines for aircraft electric propulsion
• New topologies of electrical machines for aircraft
• Fault diagnosis for aircraft electrical machines
• Fault-tolerant electrical machines for aircraft application |

The rotor position and speed are crucial for the high-performance AC motor drives. Drives without motor-mounted mechanical sensors provide reduced system costs with increased reliability and robustness. Therefore, sensorless (also noted as self-sensing) that requires no additional mechanical sensors has become attractive in the last few decades, and has been commercialized and widely used in industrial applications.
Nevertheless, some key challenges and unresolved problems still remain, which limit the sensorless control applications. The sensorless operation in the extreme speed range from the zero stator-frequency to the deep field-weakening for a long time is a big challenge. The co-design of motor and sensorless control, the emerging applications for sensorless drives, the robustness against non-linearity impact, time-varying parameters etc., also need further research.
In this scenario, this special session is timely to show the up-to-date improvement of sensorless control for AC motor drives.
Topics of interest include, but are not limited to, trends, design, technology and applications in the following sectors:
• Signal-injection-based and back-emf-based sensorless methods
• Co-design for motor and sensorless control
• Sensorless control in extreme speed range
• Sensorless self-commissioning and parameter adaptation
• Non-linearity impact: prediction and compensation
• Emerging applications for sensorless drives |

This session deals with the design, control, and practical applications of switched reluctance motor(SRM). SRMs are robust and simple in structure with high power density without having any permanent magnet. Nowadays, SRMs have been adopted for electric vehicles, aerospace, and various high-speed applications for industrial and home appliances.
In the special session, research results of advanced designs and control schemes to solve present practical problems are discussed in detail. |

In the existing ground-based train control system, there are some limitations in increasing transportation because of increases of safety distance with the preceding train. To overcome these limitations, a change in the train control paradigm to the next-phase-centered train autonomous driving control system is needed. Therefore, in this session, the development status and issues of interesting technologies related to autonomous train control, which have been recently studied in Korea, will be discussed.
• Design of SITL based simulator for autonomous train control system
• Concepts and operational scenarios on virtual coupling technologies
• Security technology that is strong against cyber attacks for autonomous train control systems
• Predictable braking model for autonomous train control
• 5G-based Wireless Communication Technology for Free Driving Control |

Advancements in power electronics and machine design allow electrical machines to be more energy-efficient and dynamic in tractions, vehicles, and wind turbines. However, high-frequency pulses from the converters and compact designs result in additional losses, stresses, and limited cooling spaces, such that failures in modern inverter-fed electrical machines occur more frequently than before. Moreover, electrical machines in drivetrains are intensively exposed to mechanical-, chemical-, dust- and thermal stresses in harsh environment and thermal cycling due to the dynamic operation. Consequently, diagnosis and prognosis of the faults in power electronics and electrical machines in such powertrains are more important and challenging than those in industrial production.
This special session therefore aims to find advanced diagnosis techniques and approaches, in order to improve the state-of-the-art for detecting incipient faults in power electronics and electrical machines.
Prospective authors are invited to submit original contributions with topics including, but not limited to:
• Fault locations: stator windings, broken bars, gearboxes, bearings, frequency converters, sensors, batteries, power supplies
• Detection quantities: vibration, current, flux, speed, temperature, and other technical variables
• Signal processing: wavelet, fuzzy logic, genetic algorithms, differential evolution, observers, active and adaptive filtering, and other artificial intelligence techniques
• Modelling and identification: Finite element analysis, model-based fault detection, parameter identification, system identification, etc.
• Prognostics and health management, remaining useful life (RUL) prediction |
