Cesar José Volpato Filho received his B.S., M.A.Sc. and Ph.D. in electrical engineering from the Federal University of Santa Maria, RS, Brazil, in 2017, 2018, and 2021, respectively. He was with the Power Electronics and Control Research Group between 2015 and 2021. Currently, he is a Postdoctoral Research Fellow at the McMaster Automotive Resource Center (MARC) at McMaster University. His main research interests include high-performance motor control techniques for switched reluctance and permanent magnet motors.

Full Profile

In 2012, Cesar began his studies in electrical engineering, at Federal University of Santa Maria (UFSM), Brazil. He joined the Power Electronics and Control Research Group (GEPOC) in 2015, where he worked with the sensorless control of induction motors. The research experience he gained at the GEPOC gave Cesar the desire and motivation to pursue a research career path through obtaining his master’s and Ph.D. 

During his master’s and Ph.D. studies, Cesar investigated the design of high-performance adaptive observers for the sensorless control of interior permanent magnet motors. He found that with such a technique, the removal of the expensive and bulky shaft encoder is possible. Furthermore, the proposed method improved the robustness characteristics of the position and speed estimation algorithm. He also investigated the effects of the parameter variation. His thesis contributions were published in prestigious IEEE journals. 

Currently, Cesar is a Postdoctoral Research Fellow at the McMaster Automotive Resource Centre (MARC) at McMaster University. With Professor Babak Nahid as his supervisor and Dr. Ali Emadi as his co-supervisor, Cesar is working with industry partner Enedym, at developing advanced switched reluctance motor drives. Cesar’s main research interests include the high-performance sensorless control methods for permanent magnet motors and switched reluctance motors.
