Soltani and H. Abootorabi Zarchi and Gh. R. Arab Markadeh}, country = {}, institution = {}, abstract = {In this paper a sliding-mode torque and flux control is designed for encoderless synchronous reluctance motor drive. The sliding-mode plus PI controllers are designed in the stator-flux field oriented reference frame which is able to track the mentioned reference signals with a minimum pulsations in the state condition. In addition, with these controllers a fast dynamic response is also achieved for the drive system. The proposed control scheme is robust subject to parameters variation except to stator resistance. To solve this problem a simple estimator is used for on-line detecting of this parameter. Moreover, the rotor position and speed are estimated by on-line obtaining of the stator-flux-space vector. The effectiveness and capability of the proposed control approach is verified by both the simulation and experimental results.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {3}, number = {10}, year = {2009}, pages = {1324 - 1330}, ee = {https://publications.waset.org/pdf/13981}, url = {https://publications.waset.org/vol/34}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 34, 2009}, }
