Development of A Complex-Vector Resolver and Its Demodulation System

By analyzing the pain points of current rotary transformer systems in aerospace starter-generator systems and considering the current state of research in academia and industry both domestically and internationally, this project aims to address the issues of positional accuracy across a wide speed range and fault tolerance under harsh conditions. It will use the complex plane excitation mechanism as a significant theoretical innovation to tackle the challenges in the field of position sensing for aerospace starter-generator systems, with the goal of enhancing operational efficiency across a wide speed domain.

Focusing on the high precision and strong fault tolerance requirements of aerospace starter-generator rotary transformer systems operating over a wide speed range, this project will investigate the coupling design of rotary transformers and demodulation systems, starting from the operational mechanisms of rotary transformers. It aims to develop a novel reluctance rotary transformer system based on the complex plane excitation mechanism, fundamentally eliminating the limitation on high-speed accuracy imposed by a single sinusoidal excitation signal in traditional rotary transformer demodulation systems. Additionally, by expanding the ports of the rotary transformer, the project intends to achieve complex plane excitation operation while effectively enhancing the fault tolerance performance of the rotary transformer, thus further improving the reliability of aerospace starter-generator systems.

Through the design and research of the complex plane excitation reluctance rotary transformer system, the project aims to provide theoretical and technical support for the optimized design and engineering implementation of high-precision reluctance rotary transformer systems. It seeks to fill the research gap in the field of aerospace starter-generator position sensors in Shenzhen, reveal system-level research patterns from whole to local in the field of reluctance rotary transformers, and expand the research perspectives and methods in the rotary transformer system domain. The implementation of this project holds significant importance for the development of the aerospace starter-generator industry and aerospace technology in Greater Bay Area.
