Co-OrganizersQiwei WangHarbin Institute of Technology

Rotor position, speed, and stator current are essential feedbacks for high-performance closed-loop control of AC motors, which were commonly sampled using multiple sensors. In recent decades, high reliability, high integration and low cost have become the development trend of advanced AC motor drives, spawning considerable emerging technologies in position or speed sensorless (also known as self-sensing) control and single current sensing, which have got broad attentions and applications by both academia and industry.

Despite the advantages of using less sensors, there are still challenges in robust observation, severe operating condition, and environmental friendliness. Rotor position observation at extreme speeds, typically the zero stator frequency and the deep field-weakening region, has long been one of the most difficult problems, especially when fewer current sensors are used. Acoustic noise and vibration which are stubborn for signal injection based sensorless control, are yet strictly prohibited in household applications. Non-linear behaviors caused by steel saturation, inverter dead time effect, and digital control etc. still need further investigation and reduction. Besides, special considerations for motor design are also critical to the control quality.

Therefore, this is a timely special session to provide the state-of-the-art research in advanced sensorless drive for AC motors.

Topics of interest include, but are not limited to, trends, design, technology and applications in the following sectors:

  • Signal-injection-based and EMF-model-based position sensorless control for AC motor drives
  • Position sensorless control using fewer current sensors
  • Position Sensorless control in extreme speed range
  • Acoustic noise and vibration reduction for sensorless control
  • Prediction and compensation for non-linearity effects
  • Parameter identification and condition monitoring of AC motors
  • Special considerations in AC motor design for sensorless control
  • Emerging applications for sensorless drives

Transportation is now one of the largest sources of greenhouse gas emissions (GHGE). To reduce carbon footprint, transportation electrification has become a new trend globally. New advances represented by maglev transportation, high-speed railway, urban rail transit, electric vehicle, electric ship, and electric aircraft technology show bright prospects in promoting sustainable development, optimizing energy mix, and enabling carbon neutrality.

To accelerate the pace of transportation electrification, the development of new battery techniques and electric machines and drives play an important role in the overall performance improvement, energy conservation, GHGE reduction, and the large-scale popularization of electrified transportation. On the other hand, with the higher and higher penetration of power electronics, electromagnetic interference and thermal management are becoming more and more important concerning the safety and reliability of electrified transportation. Additionally, the development of new machine theory and high-efficiency power converters in recent years has triggered the emergence of new structural motors and new control philosophies, and the electrified transportation has been ready for another wave of development, but also exposes some technical problems related to these new applications and therefore needs to be effectively and urgently addressed.

Rare-earth materials are broadly used for energy conversion and electrical traction machines. With the rising mining cost, environmental pollution, and scarcity of rare earth resources, rare-earth-free reluctance machines are gaining more attention, such as synchronous reluctance machines, switched reluctance machines, vernier reluctance machines, etc. Developing control techniques for reluctance machines is essential to maximize the power capability and optimize the operating performance.

The control of reluctance machines faces challenges due to the unique stator-rotor structure, saturated magnetic characteristics, and nonlinear current trajectories. Specifically, the active utilization of the saturation region brings difficulties in regulating the phase current and shaft torque. The severe nonlinearity prevents adapting advanced control methods to reluctance machine applications. Parameters mismatching during long-time service also affects the control performance.  

Therefore, a timely special session is held to discuss the recent progress in advanced control strategies for reluctance machines.

The special session includes, but is not limited to, the following topics:

  • New reluctance machine structure and control
  • New power converter topology and control
  • Condition monitoring and fault diagnosis
  • Torque regulation and efficiency optimization
  • Parameter measurement and estimation
  • Powertrain design using reluctance machines
  • Artificial intelligence in reluctance machine drives

Development of power electronic converters tend to achieve high efficiency and high power density in both academic and industry. High frequency operation can effectively reduce the volume of passive components.  Additionally, the emerging wide band gap semiconductors can push the switching frequency to several mega hertz. This has been widely studied in recent research work.

However, high frequency will cause a series of drawbacks such as high switching losses, high winding or magnetic core losses from passive components and narrow output load range. Therefore, in order to solve the contradiction between efficiency and power density, improvements can be made in aspects such as topology, drive circuit and magnetic devices and etc.

Thus, this special issue intends to focus on the latest research and demonstrate emerging topics in high frequency high power density power conversion technologies. Topics of interest include, but are not limited to:

  • High power density topologies
  • Advanced high frequency modeling and control strategies
  • Soft switching technologies
  • Wide bandgap semiconductors applications
  • Wide bandgap semiconductors driving strategies
