— The goal of this paper is to design a high performance speed controller for a PMSM drive. The controller is passivity based using the energy shaping technique namely Interconnection and Damping Assignment. Under some assumptions, a linear controller is derived associated to a non linear observer to estimate the load torque which is unknown. The important(More)
—This paper presents a specific controller architecture devoted to obtain a Permanent Magnet Synchronous Motor drive robust to mechanical sensor failure. In order to increase the reliability which is a key issue in industrial and transportation applications (Electric or Hybrid ground vehicle or aerospace actuators) two virtual sensors (a two stage Extended(More)
