N2 - This study proposes a novel online enhanced efficiency control (OEEC) using a low computational burden method to improve the efficiency of the synchronous reluctance motor (SynRM) drive. First, a conventional maximum torque per ampere control (CMTPAC) is presented. However, the efficiency of the CMTPAC does not show a considerable improvement due to the severe saturation of SynRM. Moreover, the reactive power is ignored in the CMTPAC. Therefore, an OEEC including the CMTPAC and modified maximum power factor control (MMPFC) is proposed to account for both active and reactive power. The MMPFC can be achieved by using a designed formula with a stator flux estimator. Furthermore, by combining the CMTPAC, the proposed OEEC can be developed without using any additional controller. Therefore, the proposed OEEC is suitable for low computational burden applications, especially in industrial applications. In addition, an adaptive nonsingular terminal sliding mode speed control is designed to improve the speed regulation of the SynRM. Finally, some experimental results are provided to verify its effectiveness.
