An improved robust field weakening algorithm for direct torque controlled synchronous reluctance motor drives
Zhang, Xinan N., Foo, Gilbert Hock Beng, Vilathgamuwa, D. Mahinda, & Maskell, D. L. (2014) An improved robust field weakening algorithm for direct torque controlled synchronous reluctance motor drives. IEEE Transactions on Industrial Electronics, 62(5), 3255 -3264.
This paper presents an improved field weakening algorithm for synchronous reluctance motor (RSMs) drives. The proposed algorithm is robust to the variations in the machine d- and q-axes inductances. The transition between the maximum torque per ampere (MTPA), current and voltage limits as well as the maximum torque per flux (MTPF) trajectories is smooth. The proposed technique is combined with the direct torque control method to attain a high performance drive in the field weakening region. Simulation and experimental results are supplemented to verify the effectiveness of the proposed approach.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
