    Prof. Xia Chaoying was born in Dec. 1958 in Hunan province. He received the degree of B.S. and M.S. from Automation Department of Tianjin University in the year 1982 and 1987, respectively. Now he is professor and doctor advisor of SEEA in Tianjin University, councilman of China Energy Society and Beijing New Energy Automobile Association, expert committee member of both Beijing New Energy Automobile Industry Alliance and Tianjin New Energy Automobile Industry Alliance, professional committee member of Chinese Institute of Aeronautics and Astronautics, member of Zhigong Party.
His research area is mainly focused on control theory and its applications, self-adaptive control, and power electronics technique. In 1997, he proposed a parameter adaptive strategy for vector control system of induction motor, which is realized under rotor coordinate. This project has been supported by state natural sciences fund, and related articles were published in magazines like Proceedings of the CSEE, Control Theory & Applications, Transactions of China Electro-technical Society, etc. In 1998, he proposed the conjecture about the stability problem of multipoint error model, and a new criterion for the absolute stability problem of the MISO/SIMO nonlinear time-varying system is obtained, related articles were published in Control Theory & Applications and Acta Automatica Sinica. In 2000, he demonstrated the theoretical defect of typical direct torque control systems, related articles were published in Control Theory & Applications.
Until 2001, he has been working on motor control system development for EV/HEV. In 2002, he undertook the “863” project “Motor and its Control System for XL Pure Electro-motion Car” of the National 10th 5-year Plan, as the project director; in 2003, he undertook the dynamic research task of the same project; in 2006, he undertook the “863” project “Development of Drive Motor System for EV-HEV” of the National 11th 5-year Plan, as the project director.
