|Co-Organizers||Qiwei Wang||Harbin Institute of Technology|
|Yao Wei||Haixi Institutes, Chinese Academy of Science|
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

- Acoustic noise and vibration reduction for sensorless control
- Prediction and compensation for non-linearity effects

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

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:
