Qianbao Mi

Northwestern Polytechnical University

Short Biography

Qianbao Mi received the B.S. and M.S. degree in Navigation Guidance and Control from Northwestern Polytechnical University, Xi'an, China, in 2005 and 2008 respectively. Then he worked in Xi'an Aerospace Precision Electromechanical Institute, engaged in the research of motor control technology. In 2019 he started Ph.D degrees in Electrical Engineering from Northwestern Polytechnical University, Xi'an, China.Since then, he has obtained senior engineer in Xi'an Aerospace Precision Electromechanical Institute. His current research interests include motor drive and motion control, parameter identification technique, and focus on sensorless field-oriented control of permanent magnet synchronous motor.

Short Description

Conventional Luenberger observer generates one-step delay, the back electromotive force(BEMF) input time and the feedback time of phase lock loop (PLL) model are in the different sequences. With the analysis of the error of Luenberger observer, a novel Luenberger observer and PLL model are proposed based on the present value observer. The estimated error of the observer was adjusted from the previous calculation to the present calculation, and the BEMF input of PLL was set at the same time as PLL feedback. Both error compensation and time compensation improved the BEMF tracking performance and position estimation accuracy.
