Abstract

Multi-phase permanent magnet synchronous motors (PMSM) are widely used in electric vehicles owing to their merits such as high efficiency, high precision and high reliability. This paper presents a novel dual measurement vector injection method (DMVIM) for dual three-phase PMSM using two hall-effect DC link current sensors. The principle of phase current reconstruction method is described as well as the basic driving system of dual three-phase PMSM. The mathematical model of dual three-phase PMSM is established. Then, the DMVIM is presented in detail and the reference voltage vector trajectories of the two windings are analyzed. Furthermore, since the extra voltage vectors are introduced with this method, the compensation algorithms of DMVIM are proposed to modify the reconstruction errors. Both the simulation results and the experimental results validate the proposed DMVIM as well as its compensation algorithms.
