Research and development of electrical drive control systems for electromobility

„The supplier of technology and services will be using its comprehensive systems and connectivity know-how to take electromobility a decisive step forward“ - Dr. Volkmar Denner, 2015

Xiaoyun Zang, Dr.

I am now senior expert in electrical drive control systems at Bosch Research and Technology Center in China. My research topics focus on motor control, sensorless control algorithms of electrical drives for electromobility. I am also looking at connected vehicle applications to further investigate big data based fault diagnosis and intelligent control strategies. I have won China Top Inventor 2019 and Bosch Inventor 2020 for data based sensor fault diagnosis.

Interview with Xiaoyun Zang, Dr.

Senior Expert Electrical Drive Systems

Please tell us what fascinates you most about research.
What fascinates me most about research is that I can always think beyond the borders. Electrical drive system control is not just to turn the rotational part, but is an interdisciplinary topic which involves a lot of areas such as power electronics, electromagnetics, sensor technology, NVH and thermal systems. It always excites me when a new topic is brought up where observing or monitoring or controlling it could help improve the performance of the system.

What makes research done at Bosch so special?
Bosch is a "giant" in electrical drive systems. Doing research at Bosch is like standing on the shoulder of the giant. Bosch is now propelling the applications of machine learning and artificial intelligence, which gives more opportunities for us to apply big data technology in electrical drive systems to explore new features and functions to improve the performance and bring USP to Bosch products.

What research topics are you currently working on at Bosch?
My team and I are now working on the sensorless control algorithms for various applications such as electrical air compressor drive in fuel cell systems, electrical compressor drive for HVAC systems in electrical vehicles, and synchronous reluctance machine drive for industrial applications. With the development of vehicle connectivity, we are also working on big data based fault diagnosis and intelligent control, trying to bring our electrical drive system knowhow and artificial intelligence together to enhance the performance of Bosch products and bring better services to customers.

What are the biggest scientific challenges in your field of research?
How to ensure our system has the best robustness is the biggest challenge in the field of electrical drive control. The system has to be stable and respond quickly upon sudden disturbances or big load change. In some instances such as autonomous driving, fault tolerant control is preferred.

How do the results of your research become part of solutions "Invented for life"?
The research results in the form of patents, algorithms, strategies and methods will be deployed in Bosch products or services to bring smoother driving experiences for drivers, better services for end users, less noisy vehicles and comfortable driving environments.
