Due to its high torque density, the interior permanent magnet synchronous machine (IPMSM) is nowadays often used in electric vehicle applications. For an efficient machine operation, a proper control strategy has to be implemented. Because of the inherent non-linearities, the control is often based on lookup tables covering the entire operating area. The proposed control strategy relies on lookup...
The compound-structure permanent-magnet synchronous machine (CS-PMSM), integrated by two electric machines, is a promising energy transducer for hybrid electric vehicles. The compound structure of CS-PMSM leads to a mechanical coupling problem, i.e. speed and torque of the two rotating shafts are correlated. Special rotor position detection and control are required. In this paper, a unified controller...
In this paper, the authors propose a novel control strategy of torque ripple reduction in hybrid vehicles. The Internal Combustion Engine (ICE) ripples are reduced by an active filter and a Permanent Magnet Synchronous Machine (PMSM). This electric motor is mounted on the crankshaft in order to generate a torque sequence opposing ripple torque. The control strategy is based on a static output feedback...
