Speech Title: Position Sensorless Control of PMSM Using Single Current Sampling
Abstract: In the realm of AC variable frequency drive systems, Permanent Magnet Synchronous Machines (PMSMs) are highly favored for their remarkable efficiency, high power density, and uncomplicated mechanical structure. Position sensorless control of PMSMs offers notable advantages in enhancing reliability and reducing system cost. However, the reliability of position sensorless control, particularly at low speeds, is impacted by the distortion of applied voltage and reconstruction error of phase current caused by the unmeasurable regions when using single DC current sampling.

This report presents the state-of-the-art of phase current reconstruction techniques using single DC current sensor along with position sensorless control. Additionally, it proposes the GINFORM (Generalized INdirect Flux detection by Online Reactance Measurement) method to minimize the negative impact of unmeasurable regions and enhance control reliability. Furthermore, a variable carrier frequency modulation strategy is introduced to improve the current loop bandwidth and dynamic performance. Experimental results are carried out to validate the effectiveness of the proposed GINFORM method. At the end, potential trends on PMSM control with fewer sensors are discussed.

Speech Title: Key Power Technologies for Electric Propulsion Aircrafts
Abstract: As the global aviation industry transitions towards sustainable development, electric propulsion technology in aircraft with new energies has become a central force driving this transformation. The electric propulsion system comprises three core electronic components: batteries, motors, and electronic controls. The technological advancements in these components are crucial to the performance and safety of electric aircraft. With improvements in the energy density of batteries, the power density of motors and controllers, as well as the miniaturization and lightweighting of related onboard electrical equipment, electric propulsion in general aviation aircraft is nearly capable of meeting the demands of the on-demand aviation market. However, this technology still faces several challenges. This report initially explores the strengths and weaknesses of electric propulsion technology and the classification of electric propulsion aircraft. It then focuses on reviewing the current research and academic progress in the three core electronic systems of batteries, motors, and electronic controls. The report delves into the key technical issues and latest research findings in these fields, discusses their specific contributions to enhancing the performance of electric propulsion systems, and also highlights the current limitations of the technology and potential directions for future research.
